PHP URL Directory - php

If the URL is the following :
If: http://www.imvu-e.com/products/dnr/
Then: http://www.imvu-e.com/products/dnr/
If: http://www.imvu-e.com/products/dnr/?
Then: http://www.imvu-e.com/products/dnr/
If: http://www.imvu-e.com/products/dnr/index.php
Then: http://www.imvu-e.com/products/dnr/
If: http://www.imvu-e.com/products/dnr/page.php?var=2
Then: http://www.imvu-e.com/products/dnr/
If: http://www.imvu-e.com/products/dnr
Then: http://www.imvu-e.com/products/
How can I do this?
My attempt:
print "http://".$_SERVER['HTTP_HOST'].dirname($_SERVER['REQUEST_URI'])."/";

Have a look at parse_url() function.
It returns anything you need.
Simply print_r() the result from parse_url to see what you get back.
You probably want something like:
$ARRurlParts = parse_url($orgurl);
$newURL = $ARRelem["scheme"].
"://".$ARRelem["host"].
((isset($ARRelem["port"]))?":".$ARRelem["port"]:"").
$ARRelem["path"];

The issue with your "attempt" is that $_SERVER['REQUEST_URI'] will contain everything the user passed, including index.php and question mark and possibly more. In order to get what you are after, you need to parse the $_SERVER['REQUEST_URI']:
If it ends with a slash /, leave it as it it
Otherwise, find the last slash in the string and take the substring from the beginning up to and including this slash
Finally append the result onto the http:// (or https:// with the domain name)

Ended up going with this
$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = substr(strtolower($_SERVER["SERVER_PROTOCOL"]), 0, strpos(strtolower($_SERVER["SERVER_PROTOCOL"]), "/")) . $s;
$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
$address = $protocol . "://" . $_SERVER['SERVER_NAME'] . $port . $_SERVER['REQUEST_URI'];
$parseUrl = parse_url(trim($address));
$parent = (substr($parseUrl['path'], -1) == '/') ? $parseUrl['path'] : dirname($parseUrl['path']) . "/";
return $parseUrl['scheme'] . '://' . $parseUrl['host'] . $parseUrl['port'] . $parent;
Inspired in part by Erwin Moller's answer (Why I voted it) and snipplets across web.

You can strip everything from the last backslash till the end of the string. I am pretty sure that dirname($_SERVER['REQUEST_URI']) won't do the job. You can also try using dirname($_SERVER['SCRIPT_FILENAME']). The last shoud work if you don't have some fancy .htaccess rewrite rules.

PHP Replace basename in the URL

I have this function.
function getCallbackUrl(){
$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
return $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] . 'response.php';
}
On my URL http://localhost/gateways/payu/index.php the above function displays URL like this http://localhost/gateways/payu/index.phpresponse.php. No idea why it is happening. The function seems correct to me. Maybe I am missing out something that I am not able to replace the base name from index.php to response.php. Any help would be truely appreciated. Thank you :)
Currently, your $_SERVER['REQUEST_URI'] itself has index.php, hence you are facing this issue, where response.php is concatenated instead of replacing. A quick fix is as below:
$_SERVER['REQUEST_URI'] = str_replace(basename($_SERVER['REQUEST_URI']),'response.php',$_SERVER['REQUEST_URI']);
return $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
You can also use a combination of parse_url(),str_replace() and basename() to achieve this.
Parse the url and get the URI path.
Get the basename of the URI.
Replace it with the one you want to.
Join these pieces together and return the URL.
Snippet:
<?php
function getCallbackUrl($url,$replacement_file){
$url_data = parse_url($url);
$url_data['path'] = str_replace(basename($url_data['path']),$replacement_file,$url_data['path']);
$url = $url_data['scheme'] . "://" . $url_data['host'] . $url_data['path'];
if(!empty($url_data['query'])) $url .= '?' . $url_data['query'];
return $url;
}
echo getCallbackUrl('http://localhost/gateways/payu/index.php','response.php');

php add GET at last string

i want to add utm_source=twitter in the of the links
i have a link let say
http://abcd.com/news?id=1
it need to be http://abcd.com/news?id=1&utm_source=twitter
if http://abcd.com/news/1
it need to be
http://abcd.com/news/1?utm_source=twitter
any idea?
To check if your link already has URL parameters on the end of it, look for the ? character in the URL. If it's there, use a & instead.
$link = 'http://abcd.com/news?id=1'; // or http://abcd.com/news
$join_char = strpos($string, '?') !== -1 ? '&' : '?'; // determine if we need & or ?
$link .= $join_char . 'utm_source=twitter';
You can check if the URL already contains a query string and branch your logic accordingly:
if (strpos($url, '?') === FALSE) {
$url .= '?utm_source=twitter';
} else {
$url .= '&utm_source=twitter';
}
If you're simply adding it to the end of a link it would look something like
$link . "?utm_source=twitter";

Format a website´s URL as a string with http:// upfront

I have a comment system that allows auto linking of url. I am using cakephp but the solution is more just PHP. here is what is happening.
if the user enters fully qualified url with http:// or https:// everything is fine.
but if they enter www.scoobydoobydoo.com it turns into http://cool-domain.com/www.scoobydoobydoo.com. basically cakephp understands that http|https is an external url so it works with http|https not otherwise.
My idea was to do some kind of str stuff on the url and get it to insert the http if not present. unfortunately whatever i try only makes it worse. I am noob :) any help / pointer is appreciated.
thanks
EDIT: posting solution snippet. may not be the best but thanks to answer at least I have something.
<?php
$proto_scheme = parse_url($webAddress,PHP_URL_SCHEME);
if((!stristr($proto_scheme,'http')) || (!stristr($proto_scheme,'http'))){
$webAddress = 'http://'.$webAddress;
}
?>
$url = "blahblah.com";
// to clarify, this shouldn't be === false, but rather !== 0
if (0 !== strpos($url, 'http://') && 0 !== strpos($url, 'https://')) {
$url = "http://{$url}";
}
Try the parse_url function: http://php.net/manual/en/function.parse-url.php
I think this will help you.
I've had a similar issue, so I created the following php function:
function format_url($url)
{
if(!$url) return null;
$parsed_url = parse_url($url);
$schema = isset($parsed_url['scheme']) ? $parsed_url['scheme'] . '://' : 'http://';
$host = isset($parsed_url['host']) ? $parsed_url['host'] : '';
$path = isset($parsed_url['path']) ? $parsed_url['path'] : '';
return "$schema$host$path";
}
if you format the following: format_url('abcde.com'), the result will be http://abcde.com.
Here is the regex: https://stackoverflow.com/a/2762083/4374834

How do I get the base URL with PHP?

I am using XAMPP on Windows Vista. In my development, I have http://127.0.0.1/test_website/.
How do I get http://127.0.0.1/test_website/ with PHP?
I tried something like these, but none of them worked.
echo dirname(__FILE__)
or
echo basename(__FILE__);
etc.
Try this:
<?php echo "http://" . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; ?>
Learn more about the $_SERVER predefined variable.
If you plan on using https, you can use this:
function url(){
return sprintf(
"%s://%s%s",
isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http',
$_SERVER['SERVER_NAME'],
$_SERVER['REQUEST_URI']
);
}
echo url();
#=> http://127.0.0.1/foo
Per this answer, please make sure to configure your Apache properly so you can safely depend on SERVER_NAME.
<VirtualHost *>
ServerName example.com
UseCanonicalName on
</VirtualHost>
NOTE: If you're depending on the HTTP_HOST key (which contains user input), you still have to make some cleanup, remove spaces, commas, carriage return, etc. Anything that is not a valid character for a domain. Check the PHP builtin parse_url function for an example.
Function adjusted to execute without warnings:
function url(){
if(isset($_SERVER['HTTPS'])){
$protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
}
else{
$protocol = 'http';
}
return $protocol . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
}
Fun 'base_url' snippet!
if (!function_exists('base_url')) {
function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){
if (isset($_SERVER['HTTP_HOST'])) {
$http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
$hostname = $_SERVER['HTTP_HOST'];
$dir = str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$core = preg_split('#/#', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
$core = $core[0];
$tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
$end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
$base_url = sprintf( $tmplt, $http, $hostname, $end );
}
else $base_url = 'http://localhost/';
if ($parse) {
$base_url = parse_url($base_url);
if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
}
return $base_url;
}
}
Use as simple as:
// url like: http://stackoverflow.com/questions/2820723/how-to-get-base-url-with-php
echo base_url(); // will produce something like: http://stackoverflow.com/questions/2820723/
echo base_url(TRUE); // will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE); // will produce something like: http://stackoverflow.com/questions/
// and finally
echo base_url(NULL, NULL, TRUE);
// will produce something like:
// array(3) {
// ["scheme"]=>
// string(4) "http"
// ["host"]=>
// string(12) "stackoverflow.com"
// ["path"]=>
// string(35) "/questions/2820723/"
// }
$base_url="http://".$_SERVER['SERVER_NAME'].dirname($_SERVER["REQUEST_URI"].'?').'/';
Usage:
print "<script src='{$base_url}js/jquery.min.js'/>";
$modifyUrl = parse_url($url);
print_r($modifyUrl)
Its just simple to use
Output :
Array
(
[scheme] => http
[host] => aaa.bbb.com
[path] => /
)
I think the $_SERVER superglobal has the information you're looking for. It might be something like this:
echo $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']
You can see the relevant PHP documentation here.
Try the following code :
$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $config['base_url'];
The first line is checking if your base url used http or https then the second line is use to get the hostname .Then the third line use to get only base folder of your site ex. /test_website/
The following code will reduce the problem to check the protocol.
The $_SERVER['APP_URL'] will display the domain name with the protocol
$_SERVER['APP_URL'] will return protocol://domain ( eg:-http://localhost)
$_SERVER['REQUEST_URI'] for remaining parts of the url such as /directory/subdirectory/something/else
$url = $_SERVER['APP_URL'].$_SERVER['REQUEST_URI'];
The output would be like this
http://localhost/directory/subdirectory/something/else
Simple and easy trick:
$host = $_SERVER['HTTP_HOST'];
$host_upper = strtoupper($host);
$path = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
$baseurl = "http://" . $host . $path . "/";
URL looks like this: http://example.com/folder/
You can do it like this, but sorry my english is not good enough.
First, get home base url with this simple code..
I've tested this code on my local server and public and the result is good.
<?php
function home_base_url(){
// first get http protocol if http or https
$base_url = (isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']!='off') ? 'https://' : 'http://';
// get default website root directory
$tmpURL = dirname(__FILE__);
// when use dirname(__FILE__) will return value like this "C:\xampp\htdocs\my_website",
//convert value to http url use string replace,
// replace any backslashes to slash in this case use chr value "92"
$tmpURL = str_replace(chr(92),'/',$tmpURL);
// now replace any same string in $tmpURL value to null or ''
// and will return value like /localhost/my_website/ or just /my_website/
$tmpURL = str_replace($_SERVER['DOCUMENT_ROOT'],'',$tmpURL);
// delete any slash character in first and last of value
$tmpURL = ltrim($tmpURL,'/');
$tmpURL = rtrim($tmpURL, '/');
// check again if we find any slash string in value then we can assume its local machine
if (strpos($tmpURL,'/')){
// explode that value and take only first value
$tmpURL = explode('/',$tmpURL);
$tmpURL = $tmpURL[0];
}
// now last steps
// assign protocol in first value
if ($tmpURL !== $_SERVER['HTTP_HOST'])
// if protocol its http then like this
$base_url .= $_SERVER['HTTP_HOST'].'/'.$tmpURL.'/';
else
// else if protocol is https
$base_url .= $tmpURL.'/';
// give return value
return $base_url;
}
?>
// and test it
echo home_base_url();
output will like this :
local machine : http://localhost/my_website/ or https://myhost/my_website
public : http://www.my_website.com/ or https://www.my_website.com/
use home_base_url function at index.php of your website and define it
and then you can use this function to load scripts, css and content via url like
<?php
echo '<script type="text/javascript" src="'.home_base_url().'js/script.js"></script>'."\n";
?>
will create output like this :
<script type="text/javascript" src="http://www.my_website.com/js/script.js"></script>
and if this script works fine,,!
I found this on
http://webcheatsheet.com/php/get_current_page_url.php
Add the following code to a page:
<?php
function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
?>
You can now get the current page URL using the line:
<?php
echo curPageURL();
?>
Sometimes it is needed to get the page name only. The following example shows how to do it:
<?php
function curPageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
echo "The current page name is ".curPageName();
?>
$http = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on'? "https://" : "http://";
$url = $http . $_SERVER["SERVER_NAME"] . $_SERVER['REQUEST_URI'];
Try this. It works for me.
/*url.php file*/
trait URL {
private $url = '';
private $current_url = '';
public $get = '';
function __construct()
{
$this->url = $_SERVER['SERVER_NAME'];
$this->current_url = $_SERVER['REQUEST_URI'];
$clean_server = str_replace('', $this->url, $this->current_url);
$clean_server = explode('/', $clean_server);
$this->get = array('base_url' => "/".$clean_server[1]);
}
}
Use like this:
<?php
/*
Test file
Tested for links:
http://localhost/index.php
http://localhost/
http://localhost/index.php/
http://localhost/url/index.php
http://localhost/url/index.php/
http://localhost/url/ab
http://localhost/url/ab/c
*/
require_once 'sys/url.php';
class Home
{
use URL;
}
$h = new Home();
?>
Base
This is the best method i think so.
$base_url = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != "off") ? "https" : "http");
$base_url .= "://".$_SERVER['HTTP_HOST'];
$base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $base_url;
The following solution will work even when the current url has request query string.
<?php
function baseUrl($file=__FILE__){
$currentFile = array_reverse(explode(DIRECTORY_SEPARATOR,$file))[0];
if(!empty($_SERVER['QUERY_STRING'])){
$currentFile.='?'.$_SERVER['QUERY_STRING'];
}
$protocol = $_SERVER['PROTOCOL'] == isset($_SERVER['HTTPS']) &&
!empty($_SERVER['HTTPS']) ? 'https' : 'http';
$url = "$protocol://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$url = str_replace($currentFile, '', $url);
return $url;
}
The calling file will provide the __FILE__ as param
<?= baseUrl(__FILE__)?>
Here's one I just put together that works for me. It will return an array with 2 elements. The first element is everything before the ? and the second is an array containing all of the query string variables in an associative array.
function disectURL()
{
$arr = array();
$a = explode('?',sprintf(
"%s://%s%s",
isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http',
$_SERVER['SERVER_NAME'],
$_SERVER['REQUEST_URI']
));
$arr['base_url'] = $a[0];
$arr['query_string'] = [];
if(sizeof($a) == 2)
{
$b = explode('&', $a[1]);
$qs = array();
foreach ($b as $c)
{
$d = explode('=', $c);
$qs[$d[0]] = $d[1];
}
$arr['query_string'] = (count($qs)) ? $qs : '';
}
return $arr;
}
Note: This is an expansion of the answer provided by maček above. (Credit where credit is due.)
Edited at #user3832931 's answer to include server port..
to form URLs like 'https://localhost:8000/folder/'
$base_url="http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].dirname($_SERVER["REQUEST_URI"].'?').'/';
Try using: $_SERVER['SERVER_NAME'];
I used it to echo the base url of my site to link my css.
<link href="//<?php echo $_SERVER['SERVER_NAME']; ?>/assets/css/your-stylesheet.css" rel="stylesheet" type="text/css">
Hope this helps!
$some_variable = substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['REQUEST_URI'], "/")+1);
and you get
something like
lalala/tralala/something/
In my case I needed the base URL similar to the RewriteBasecontained in the .htaccess file.
Unfortunately simply retrieving the RewriteBase from the .htaccess file is impossible with PHP. But it is possible to set an environment variable in the .htaccess file and then retrieve that variable in PHP. Just check these bits of code out:
.htaccess
SetEnv BASE_PATH /
index.php
Now I use this in the base tag of the template (in the head section of the page):
<base href="<?php echo ! empty( getenv( 'BASE_PATH' ) ) ? getenv( 'BASE_PATH' ) : '/'; ?>"/>
So if the variable was not empty, we use it. Otherwise fallback to / as default base path.
Based on the environment the base url will always be correct. I use / as the base url on local and production websites. But /foldername/ for on the staging environment.
They all had their own .htaccess in the first place because the RewriteBase was different. So this solution works for me.
Currently this is the proper answer:
$baseUrl = $_SERVER['REQUEST_SCHEME'];
$baseUrl .= '://'.$_SERVER['HTTP_HOST'];
You might want to add a / to the end. Or you might want to add
$baseUrl .= $_SERVER['REQUEST_URI'];
so in total copy paste
$baseUrl = $_SERVER['REQUEST_SCHEME']
. '://' . $_SERVER['HTTP_HOST']
. $_SERVER['REQUEST_URI'];
function server_url(){
$server ="";
if(isset($_SERVER['SERVER_NAME'])){
$server = sprintf("%s://%s%s", isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http', $_SERVER['SERVER_NAME'], '/');
}
else{
$server = sprintf("%s://%s%s", isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http', $_SERVER['SERVER_ADDR'], '/');
}
print $server;
}
I had the same question as the OP, but maybe a different requirement. I created this function...
/**
* Get the base URL of the current page. For example, if the current page URL is
* "https://example.com/dir/example.php?whatever" this function will return
* "https://example.com/dir/" .
*
* #return string The base URL of the current page.
*/
function get_base_url() {
$protocol = filter_input(INPUT_SERVER, 'HTTPS');
if (empty($protocol)) {
$protocol = "http";
}
$host = filter_input(INPUT_SERVER, 'HTTP_HOST');
$request_uri_full = filter_input(INPUT_SERVER, 'REQUEST_URI');
$last_slash_pos = strrpos($request_uri_full, "/");
if ($last_slash_pos === FALSE) {
$request_uri_sub = $request_uri_full;
}
else {
$request_uri_sub = substr($request_uri_full, 0, $last_slash_pos + 1);
}
return $protocol . "://" . $host . $request_uri_sub;
}
...which, incidentally, I use to help create absolute URLs that should be used for redirecting.
Just test and get the result.
// output: /myproject/index.php
$currentPath = $_SERVER['PHP_SELF'];
// output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index )
$pathInfo = pathinfo($currentPath);
// output: localhost
$hostName = $_SERVER['HTTP_HOST'];
// output: http://
$protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https://'?'https://':'http://';
// return: http://localhost/myproject/
echo $protocol.$hostName.$pathInfo['dirname']."/";
$http = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on'? "https://" : "http://";
$dir = str_replace(basename($_SERVER['SCRIPT_NAME']), '',$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME']);
echo $url = $http . $dir;
// echo $url = $http . $_SERVER["SERVER_NAME"] . $_SERVER['REQUEST_URI'];

How can I get the current page's full URL on a Windows/IIS server?

I moved a WordPress installation to a new folder on a Windows/IIS server. I'm setting up 301 redirects in PHP, but it doesn't seem to be working. My post URLs have the following format:
http:://www.example.com/OLD_FOLDER/index.php/post-title/
I can't figure out how to grab the /post-title/ part of the URL.
$_SERVER["REQUEST_URI"] - which everyone seems to recommend - is returning an empty string. $_SERVER["PHP_SELF"] is just returning index.php. Why is this, and how can I fix it?
Maybe, because you are under IIS,
$_SERVER['PATH_INFO']
is what you want, based on the URLs you used to explain.
For Apache, you'd use $_SERVER['REQUEST_URI'].
$pageURL = (#$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
if ($_SERVER["SERVER_PORT"] != "80")
{
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
}
else
{
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
For Apache:
'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']
You can also use HTTP_HOST instead of SERVER_NAME as Herman commented. See this related question for a full discussion. In short, you are probably OK with using either. Here is the 'host' version:
'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']
For the Paranoid / Why it Matters
Typically, I set ServerName in the VirtualHost because I want that to be the canonical form of the website. The $_SERVER['HTTP_HOST'] is set based on the request headers. If the server responds to any/all domain names at that IP address, a user could spoof the header, or worse, someone could point a DNS record to your IP address, and then your server / website would be serving out a website with dynamic links built on an incorrect URL. If you use the latter method you should also configure your vhost or set up an .htaccess rule to enforce the domain you want to serve out, something like:
RewriteEngine On
RewriteCond %{HTTP_HOST} !(^stackoverflow.com*)$
RewriteRule (.*) https://stackoverflow.com/$1 [R=301,L]
#sometimes u may need to omit this slash ^ depending on your server
Hope that helps. The real point of this answer was just to provide the first line of code for those people who ended up here when searching for a way to get the complete URL with apache :)
$_SERVER['REQUEST_URI'] doesn't work on IIS, but I did find this: http://neosmart.net/blog/2006/100-apache-compliant-request_uri-for-iis-and-windows/ which sounds promising.

"http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
echo $url;
}
Then just call the my_url function.
I use the following function to get the current, full URL. This should work on IIS and Apache.
function get_current_url() {
$protocol = 'http';
if ($_SERVER['SERVER_PORT'] == 443 || (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on')) {
$protocol .= 's';
$protocol_port = $_SERVER['SERVER_PORT'];
} else {
$protocol_port = 80;
}
$host = $_SERVER['HTTP_HOST'];
$port = $_SERVER['SERVER_PORT'];
$request = $_SERVER['PHP_SELF'];
$query = isset($_SERVER['argv']) ? substr($_SERVER['argv'][0], strpos($_SERVER['argv'][0], ';') + 1) : '';
$toret = $protocol . '://' . $host . ($port == $protocol_port ? '' : ':' . $port) . $request . (empty($query) ? '' : '?' . $query);
return $toret;
}
REQUEST_URI is set by Apache, so you won't get it with IIS. Try doing a var_dump or print_r on $_SERVER and see what values exist there that you can use.
The posttitle part of the URL is after your index.php file, which is a common way of providing friendly URLs without using mod_rewrite. The posttitle is actually therefore part of the query string, so you should be able to get it using $_SERVER['QUERY_STRING']
Use the following line on the top of the PHP page where you're using $_SERVER['REQUEST_URI']. This will resolve your issue.
$_SERVER['REQUEST_URI'] = $_SERVER['PHP_SELF'] . '?' . $_SERVER['argv'][0];
Oh, the fun of a snippet!
if (!function_exists('base_url')) {
function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){
if (isset($_SERVER['HTTP_HOST'])) {
$http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
$hostname = $_SERVER['HTTP_HOST'];
$dir = str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$core = preg_split('#/#', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
$core = $core[0];
$tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
$end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
$base_url = sprintf( $tmplt, $http, $hostname, $end );
}
else $base_url = 'http://localhost/';
if ($parse) {
$base_url = parse_url($base_url);
if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
}
return $base_url;
}
}
It has beautiful returns like:
// A URL like http://stackoverflow.com/questions/189113/how-do-i-get-current-page-full-url-in-php-on-a-windows-iis-server:
echo base_url(); // Will produce something like: http://stackoverflow.com/questions/189113/
echo base_url(TRUE); // Will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE); //Will produce something like: http://stackoverflow.com/questions/
// And finally:
echo base_url(NULL, NULL, TRUE);
// Will produce something like:
// array(3) {
// ["scheme"]=>
// string(4) "http"
// ["host"]=>
// string(12) "stackoverflow.com"
// ["path"]=>
// string(35) "/questions/189113/"
// }
Everyone forgot http_build_url?
http_build_url($_SERVER['REQUEST_URI']);
When no parameters are passed to http_build_url it will automatically assume the current URL. I would expect REQUEST_URI to be included as well, though it seems to be required in order to include the GET parameters.
The above example will return full URL.
I have used the following code, and I am getting the right result...
<?php
function currentPageURL() {
$curpageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {
$curpageURL.= "s";
}
$curpageURL.= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$curpageURL.= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
}
else {
$curpageURL.= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $curpageURL;
}
echo currentPageURL();
?>
In my apache server, this gives me the full URL in the exact format you are looking for:
$_SERVER["SCRIPT_URI"]
Reverse Proxy Support!
Something a little more robust. Note It'll only work on 5.3 or greater.
