What strategies can be employed to simplify and optimize PHP code for handling URL parameters effectively?

When handling URL parameters in PHP, it is important to simplify and optimize the code to improve readability and performance. One strategy is to use the $_GET superglobal array to access and process URL parameters efficiently. Additionally, sanitizing and validating input data can help prevent security vulnerabilities. 

// Simplified and optimized code for handling URL parameters in PHP
if(isset($_GET['param'])) {
    $param = $_GET['param'];
    // Sanitize and validate the parameter before using it
    $sanitized_param = filter_var($param, FILTER_SANITIZE_STRING);
    
    // Use the sanitized parameter in your code
    echo "Parameter: " . $sanitized_param;
}
