How can debugging techniques be utilized in PHP to troubleshoot issues related to passing and processing URL parameters in server requests?

When troubleshooting issues related to passing and processing URL parameters in server requests in PHP, one effective debugging technique is to use the `var_dump()` function to inspect the values of the parameters being passed. This can help identify any errors in the parameter values or how they are being processed in the code. 

// Debugging URL parameters in PHP
var_dump($_GET); // Inspect the values of the URL parameters

// Process URL parameters
if(isset($_GET['param1']) && isset($_GET['param2'])) {
    $param1 = $_GET['param1'];
    $param2 = $_GET['param2'];

    // Perform operations with the parameters
    // ...
} else {
    echo "Missing required parameters";
}
