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

Accessing URL Query String Parameters with Minimal Code

In this question, the asker seeks a concise method to extract the query string parameter from a URL. Typically, to retrieve the parameter using PHP, one would utilize the $_GET superglobal. However, an alternative approach requires less code.

To obtain the desired result, we can utilize the $_SERVER superglobal. Specifically, the $_SERVER['QUERY_STRING'] element contains the complete query string, including the parameter.

Code Example:

// Example URL: www.mysite.com/category/subcategory?myqueryhash

// Get the query string
$query_string = $_SERVER['QUERY_STRING'];

// Extract the parameter value
$parameter_value = strstr($query_string, '?').substr(strstr($query_string, '?'), 1);

// Output the result
echo $parameter_value;  // Output: myqueryhash
