What strategies can be used to debug and troubleshoot URL parameter passing issues in PHP applications?

URL parameter passing issues in PHP applications can often be debugged and troubleshooted by checking the syntax of the URL parameters being passed, ensuring that the correct parameter names are used, and verifying that the parameters are being properly processed by the PHP script. 

// Check if the URL parameter is set and not empty
if(isset($_GET['parameter_name']) && !empty($_GET['parameter_name'])) {
    // Process the parameter value
    $parameter_value = $_GET['parameter_name'];
    // Use the parameter value in your application logic
    // For example, echo the parameter value
    echo $parameter_value;
} else {
    // Handle the case when the parameter is not set or empty
    echo "Parameter not found or empty";
}
