Stripping query parameter is very useful when you want to create a URL dynamically based on some conditions. The preg_replace() function is the easiest way to remove a specific parameter and its value from URL query string using PHP. PHP preg_replace() function searches string for matches to pattern and replace with the replacement. Use preg_replace() with REGEX to remove parameter from query string using PHP.

In the following code snippet shows how you can remove specific query string variable from URL in PHP.
<pre>$key&nbsp;=&nbsp;'page';
$url = 'http://ec2-13-127-91-65.ap-south-1.compute.amazonaws.com/?type=product&amp;page=5';

//&nbsp;Remove&nbsp;specific&nbsp;parameter&nbsp;from&nbsp;query&nbsp;string
$filteredURL&nbsp;=&nbsp;preg_replace('~(\?|&amp;)'.$key.'=[^&amp;]*~',&nbsp;'$1',&nbsp;$url);</pre>

$currentURL&nbsp;=&nbsp;$protocol&nbsp;.&nbsp;$_SERVER['HTTP_HOST']&nbsp;.&nbsp;$_SERVER['REQUEST_URI'];

$key&nbsp;=&nbsp;'page';

$filteredURL&nbsp;=&nbsp;preg_replace('~(\?|&amp;)'.$key.'=[^&amp;]*~',&nbsp;'$1',&nbsp;$currentURL);</pre>
