how to take the link with its variables from the page - php

how can i take the link of the page that i am on with its variables ?
example i have the page link is
article.php?article_id=10&article_title=title&lang=ar
when i use the $_SERVER['SCRIPT_NAME'] variable it takes only article.php
and im rewriting the url as well so it looks like this
article/10/title/ar
what i want to do is just make a link that is to an English page so im trying to make it look like this
article/10/title/en
how can i do that?

Since the data looks like its passed with a HTTP GET method, you can use this
$_GET["lang"];
This returns the value assigned to "lang"

$_SERVER['QUERY_STRING'] will have all the parameters. You can also check $_SERVER['REQUEST_URI'] and that should contain the whole url, file and parameters.

Something like:
$params = $_GET;
$params['lang'] = 'en';
$link = basename($_SERVER['SCRIPT_NAME']) . implode('/', $params);

Send URL as a Query String

Think my current page url is:
http://example.com/id=10
In this this page has link to go other page, I want to pass current URL as a query string like this:
http://example.com/about-us/?edit=1&return=http://example.com/id=10
in PHP
http://example.com/about-us/?edit=1&return=<?php echo $_SERVER['QUERY_STRING'] ?>
but this is not working, could anyone help me to do this.
Use this (I assume you are using http only);
$currentUrl = urlencode("http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
$link = "http://example.com/about-us/?edit=1&return=" . $currentUrl;
use urlencode($_SERVER['QUERY_STRING'])
It encodes the link.

How can I get current page name including $_GET variable in URL?

Let's say I have the page:
index.php?page=page-title-here
I want to get the current page name including the $_GET variable in the URL.
I am currently using this:
basename(__FILE__)
It outputs "index.php", the actual file name. Any idea how to also include the $_GET variable so that it will output "index.php?page=page-title-here"?
The variable $_SERVER["REQUEST_URI"] gives you the file with GET parameters. Also includes folders in the url.
Edit: Use $page = end(explode('/', $_SERVER["REQUEST_URI"])); if you want to get rid of the folders from the url.
You can do so using the REQUEST_URI:
echo $_SERVER['REQUEST_URI'];
From the manual:
REQUEST_URI: The URI which was given in order to access this page; for instance
Try...
$page = (__FILE__) . '?' . $_GET['page'];
Try $_SERVER['REQUEST_URI'] (there are lots of interesting things in $_SERVER)
Use:
basename($_SERVER['REQUEST_URI'])

Php How do you redirect without copying the same url query

I am validating a form on a page and I need to redirect back to the same page with the same url query and a additional &valid=false at the end of the query when redirected.
How would you do this so that the url is not repeated on redirect:
http://test.com/index.php?a=1&b=2&valid=false&a=1&b=2&valid=false
I am using $_SERVER['REQUEST_URI']
There are many ways to do it, here is a simple one:
$url = $_SERVER['REQUEST_URI'];
if (!isset($_GET['valid'])) {
$url.='&valid=false'; //assuming there are always additional parameters, otherwise you must check whether to use '?' or '&'
}
But you can also use parse_url(), strpos(), regular expressions etc
You can use of http_build_query() after modifying parameters:
<?php
$_GET['a'] = 1;
$_GET['b'] = 2;
$_GET['valid'] = 'true';
$url = $_SERVER['SCRIPT_NAME'].'?'.http_build_query($_GET);
?>
Like that, if $_GET['valid'] is not defined then it will be created, else it will be modified.

PHP - Get string from URL

by having an URL like this: mysite.com/subfolder/helloworld - Is it possible to read the "helloworld" from within a PHP page?
I would like to use the string as a part to load some content.
end( explode( '/', $_SERVER['REQUEST_URI'] ) )
without the end() call it will give you all the parts of the URL
You should read about URL rewriting.
This is more clean than "reading" the current URL. Basically you can redirect your URL (transparently) to something like :
mysite.com/index.php?folder=subfolder&category=helloworld
Then in PHP, you can access the URL parameter with :
$folder = $_GET['subfolder']
$category = $_GET['category']
This is maybe not the kind of answer you were expecting, but it can be interesting to know.
The request url (everything from the first / after the domain name) can be found in $_SERVER["REQUEST_URI"]
Hello have u used 'strstr' keyword of php?
please try like this
if(strstr($_SERVER["REQUEST_URI"], "helloworld"))
return true;
else
return false;
May be this will be helpful to you.

Doing a URL re-write while using PHP GET method

When I click on a comment section for a given entry on a site I have, the URL looks like this:
http://www...com/.../comments/index.php?submission=Portugal%20Crushes%20North%20Korea&submissionid=62&url=nytimes.com/2010/06/22/sports/soccer/22portugalgame.html?hpw&countcomments=3&submittor=johnjohn12&submissiondate=2010-06-21%2019:00:07&dispurl=nytimes.com
I want to make it look like this URL:
http://www...com/.../comments/Portugal-Crushes-North-Korea-62
I understand that this involves adding rules to the .htaccess file. I have two questions:
Since I am using the GET method in PHP, the ugly URL has a bunch of variables appended to it. I don't want all of these variables to appear in the clean URL. Is it possible to only include a few of the variables in the clean URL but still have a rule directing it to an ugly URL with all of the variables?
Once I have the .htaccess rules written, do I go back and change the links in the source code to direct to the clean URLs? If so, how do I do this using the GET method when the clean URL does not have all of the variables that I want to pass along?
Thanks in advance,
John
I'm not sure why you need all that data in the URL. You should be storing things like the submission title, its date and author in a database and then refer to it with an ID. That way, your URLs will be shorter and prettier:
http://www.example.org/article.php?id=1
http://www.example.org/article/1/
You can accomplish this with a simple RewriteRule in your .htaccess file, like so:
RewriteEngine On
RewriteRule ^articles/([0-9]+)/ article.php?id=$1
No, you can not leave variables out and expect them to be passed anyway. If you do this, the information is no longer in the URL, so you don't have a way to get it.
You can use post instead of get if you want to pass variables without them showing up in the URL.
I join the word of Sjoerd, but there are a lot of ways how you can rewrite your url like you want to!
Apache and (IIS too) supports url-s like this one: http://example.com/index.php/my-rewritten-url_62
function URISegment($segment)
{
$uri_array = explode('/',$_SERVER['REQUEST_URI']);
$uri_count = count($uri_array);
$returning_uri = array();
for($i = 0;$i<$uri_count;$i++)
{
if(empty($uri_array[$i]) || $uri_array[$i] == "index.php")
unset($uri_array[$i]);
else
array_push($returning_uri,$uri_array[$i]);
}
if($segment < count($returning_uri))
return $returning_uri[$segment];
else
return false;
}
This works, but you need to define the base url too, and this needs to be called at the beginning of the file, and implemented at every image, script, etc. call.
function BaseURL()
{
if(isset($_SERVER['HTTP_HOST']))
{
$base = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ? 'https' : 'http';
$base .= '://'. $_SERVER['HTTP_HOST'];
$base .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
}
else
{
$base = 'http://localhost/';
}
return $base;
}
After this you can use instead of this:
// http://example.com/?MyKey=Some-data
$MyKey = $_GET['MyKey']; //which is the first item
echo $MyKey;
// results: Some-data
This:
// http://example.com/?MyKey=Some-data
$MyKey = URISegment(0);
echo $MyKey;
// results: Some-data
You've got the same result by each one.
PS:
I like this solution because I can mix url types as I need them like:
example.com/index.php/index/evaled-article?some=db-stored&code=snipplet
And of course you can rewrite your url like FRKT said :)
And of course, if you want to hide the index.php you need to use mod_rewrite, because there's no way
