replace urls variable value - php

I have the following url
/index.php?option=com_zoo&task=item&item_id=292&Itemid=283
What I want to do to replace item_id's value with a variable. I have been checking a couple of php functions like split and parse_str, but I do not know how I to get it to work.

$url = '/index.php?option=com_zoo&task=item&item_id=292&Itemid=283';
$query = explode('?', $url); // Split the URL on `?` to get the query string
parse_str($query[1], $data); // Parse the query string into an array
echo $data['item_id']; // 292
$newValue = 300;
$data['item_id'] = $newValue; // Replace item_id's value
$url = $query[0].'?'.http_build_query($data); // rebuild URL
echo $url; // '/index.php?option=com_zoo&task=item&item_id=300&Itemid=283";

Try the str_replace function. If you have your URL stored in the variable $url and the variable you want to replace Itemid stored in $ItemID:
$url = str_replace("Itemid", $ItemID, $url);

*this is the exact way of doing it *
<?php
$url = '/index.php?option=com_zoo&task=item&item_id=292&Itemid=283';
$explodeData =parse_url($url);
$dataReplace = str_replace('item_id','replacedvariable',$explodeData['query'],$count);
$changedUrl = $explodeData['path']."?".$dataReplace;
echo $changedUrl;
?>

Need to change url using php

I am going to make a URL checking system.
I have this URL
https://lasvegas.craigslist.org/mob/6169799901.html
Now I want to make this URL like this
https://lasvegas.craigslist.org/search/mob?query=6169799901
how can I do it using PHP?
Since I ended up (maybe?) solving it anyways, here's one method using URL/path parsing:
$url = 'https://lasvegas.craigslist.org/mob/6169799901.html';
$parsed = parse_url($url);
$basepath = pathinfo($parsed['path']);
echo $parsed['scheme'].
"://".
$parsed['host'].
"/search".
$basepath['dirname'].
"?query=".
$basepath['filename'];
Formatted for readability.
https://3v4l.org/E6Y54
Try this
$url = "https://lasvegas.craigslist.org/mob/6169799901.html";
$id = substr($url, strrpos($url, '/') + 1);
$id = str_replace(".html","",$id);
$result = "https://lasvegas.craigslist.org/search/mob?query=".$id;
echo $result;

Internal Server Error when trying to check url

I'm trying to check the string after the last trailing slash in my URL.
My code is as follows:
$url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$data = substr($url, strrpos($url, '/') + 1);
if($data == "dashboard") {
require_once VIEW_ROOT . '/cp/dashboard_view.php';
} else {
echo $data;
}
Once I go to http://MYURL/dashboard/in it should show in as the $data. Instead it gives me a 500 error.
You can simply use explode() function to break the string... .Or else $_SERVER[REQUEST_URI] shall give you the data after the host name...
But for the data after the last '/' explode function will work the best..
This will work.
$url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$x = explode('/',$url);
$data = $x[sizeof($x)-1];
echo $data;
You should try :
$url = "http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI];
You need to join
http:// string with $_SERVER[HTTP_HOST] and then $_SERVER[REQUEST_URI] using .(dot).

Replace the page from a url using php

I have this type of urls stored in a php variable:
$url1 = 'https://localhost/mywebsite/help&action=something';
$url2 = 'https://localhost/mywebsite/jobs&action=one#profil';
$url3 = 'https://localhost/mywebsite/info&action=two&action2=something2';
$url4 = 'https://localhost/mywebsite/contact&action=one&action2=two#profil';
I want to replace the page help, jobs, info, contact with home in a very simple way, something like this:
echo replaceUrl($url1);
https://localhost/mywebsite/home&action=something
echo replaceUrl($url2);
https://localhost/mywebsite/home&action=one#profil
echo replaceUrl($url3);
https://localhost/mywebsite/home&action=two&action2=something2
echo replaceUrl($url4);
https://localhost/mywebsite/home&action=one&action2=two#profil
So here is the solution i found:
function replaceUrl($page){
$pieces = explode("/", $page);
$base = '';
for ($i=0; $i<count($pieces)-1; $i++) $base .= $pieces[$i].'/';
$hash = strpbrk($pieces[count($pieces)-1], '&#');
return $base.'home'.$hash;
}
You'll want to add something like
RedirectMatch 301 help(.*) home$1
to your .htaccess file. I'm not sure PHP is the correct tool for the job.
If you actually want to modify a string with the value of that (which is what your tags and.. comments indicate), you'll want to do:
$url = "https://localhost/mywebsite/help&action=something#profil"
$url = str_replace("help", "home", $url);
echo $url; // https://localhost/mywebsite/home&action=something#profil

URL Replacement in PHP

I'm trying to change a value in a string that's holding my current URL. I'm trying to get something like
http://myurl.com/test/begin.php?req=&srclang=english&destlang=english&service=MyMemory
to look like
http://myurl.com/test/end.php?req=&srclang=english&destlang=english&service=MyMemory
replacing begin.php for end.php.
I need the end.php to be stored in a variable so it can change, but begin.php can be a static string.
I tried this, but it didn't work:
$endURL = 'end.php';
$beginURL = 'begin.php';
$newURL = str_ireplace($beginURL,$endURL,$url);
EDIT:
Also, if I wanted to replace
http://myurl.com/begin.php?req=&srclang=english&destlang=english&service=MyMemory
with
http://newsite.com/end.php?req=&srclang=english&destlang=english&service=MyMemory
then how would I go about doing that?
Assuming that you want to replace the script filename of the url, you can use something like this :
<?php
$endURL = 'end.php';
$url ="http://myurl.com/test/begin.php?req=&srclang=english&destlang=english&service=MyMemory";
$pattern = '/(.+)\/([^?\/]+)\?(.+)/';
$replacement = '${1}/'.$endURL.'?${3}';
$newURL = preg_replace($pattern , $replacement, $url);
echo "url : $url <br>";
echo "newURL : $newURL <br>";
?>
How do you want them to get to end.php from beigin.php? Seems like you can just to a FORM submit to end.php and pass in the variables via POST or GET variables.
The only way to change what page (end.php, begin.php) a user is on is to link them to another page from that page, this requires a page refresh.
I recently made a PHP-file for this, it ended up looking like this:
$vars = $_SERVER["QUERY_STRING"];
$filename = $_SERVER["PHP_SELF"];
$filename = substr($filename, 4);
// for me substr removed 'abc/' in the beginning of the string, you can of course adjust this variable, this is the "end.php"-variable for you.
if (strlen($vars) > 0) $vars = '?' . $vars;
$resultURL = "http://somewhere.com" . $filename . $vars;

Replacing a specific part of a query string PHP

I use $_SERVER['QUERY_STRING'] to get the query sting.
A example would be a=123&b=456&c=789
How could I remove the b value from the query string to obtain a=123&c=789 where b can be any value of any length and is alpha numeric.
Any ideas appreciated, thanks.
A solution using url parsing:
parse_str($_SERVER['QUERY_STRING'], $result_array);
unset($result_array['b']);
$_SERVER['QUERY_STRING'] = http_build_query($result_array);
The value is going to be $_GET['b'].
How about:
str_replace('&b='.$_GET['b'], '', $_SERVER['QUERY_STRING']);
you can use this function:
function Remove_QS_Key($url, $key) {
$url = preg_replace('/(?:&|(\?))'.$key.'=[^&]*(?(1)&|)?/i', "$1", $url);
return $url;
}
to remove any key you want, e.g.
echo Remove_QS_Key("http://domain.com/?a=b&ref=dusername&c=d&e=f&g=h", "ref");
result
http://www.domain.com/?a=b&c=d&e=f&g=h
Try this:
$query_new = preg_replace('/(^|&)b=[^&]*/', '', $query);
All the answers look good, but it will be more flexible if you do:
// Make a copy of $_GET to keep the original data
$getCopy = $_GET;
unset($getCopy['b']); // or whatever var you want to take out
// This is your cleaned array
var_dump($getCopy);
// If you need the URL-encoded string, just use http_build_query()
$encodedString = http_build_query($getCopy);
You simply make a variable using $_GET and exclude b query string in build process:
$query_string_new = 'a=' . urlencode($_GET['a']) . '&c=' . urlencode($_GET['c']);
The $query_string_new should now contain a=123&c=789
Pear already has a class(Net_URL2) that handles URL parsing/building:
Install via Composer: https://packagist.org/packages/pear/net_url2
Install as include: https://github.com/pear/Net_URL2/blob/master/Net/URL2.php
Example code:
$url = new Net_URL2('http://www.example.com/?one=1');
$url->setQueryVariable('two', 2);
echo $url; // http://www.example.com/?one=1&two=2
Here is a function to replace a query parameter: (like example.com?a=1&b=2 -> example.com?a=5&b=2)
function replace_qs_key($key, $value) {
$current_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") .
"://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$current_url_without_qs = strtok($current_url, '?');
parse_str($_SERVER['QUERY_STRING'], $query_params);
$query_params['page'] = $value;
$_SERVER['QUERY_STRING'] = http_build_query($query_params);
$new_url = $current_url_without_qs .'?'. $_SERVER['QUERY_STRING'];
return $new_url;
}
