How Can I Efficiently Extract URL Query String Parameters in PHP?

Get URL Query String Parameters

Often, you may need to retrieve specific parameters from a URL query string. For instance, consider the following URL:

www.mysite.com/category/subcategory?myqueryhash

In this case, we want to extract the myqueryhash parameter. While it's possible to use $_GET for this purpose, a more concise approach is available.

"Less Code Needed" Approach

To obtain the query string parameters without using the $_GET array, you can utilize the $_SERVER['QUERY_STRING'] variable. This variable contains the entire query string without any processing or parsing, making it a straightforward method to access the desired parameter.

For the above example, the following code snippet will output myqueryhash:

<?php
   echo $_SERVER['QUERY_STRING'];
?>
