Are there any common pitfalls associated with misusing URL and URI in PHP programming?

Misusing URL and URI in PHP programming can lead to security vulnerabilities such as injection attacks or incorrect data handling. To avoid these pitfalls, always sanitize and validate user input when working with URLs and URIs. 

// Example of sanitizing and validating a URL in PHP
$url = filter_var($_GET['url'], FILTER_SANITIZE_URL);
if (filter_var($url, FILTER_VALIDATE_URL)) {
    // Proceed with using the sanitized and validated URL
} else {
    // Handle invalid URL input
}
