Are there any specific PHP functions or methods that should be used when working with dynamic IDs in URLs?

When working with dynamic IDs in URLs, it is important to properly sanitize and validate the input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One way to handle dynamic IDs is to use PHP functions like `filter_input()` or `filter_var()` to sanitize and validate the input before using it in your application. 

// Example of sanitizing and validating a dynamic ID from the URL
$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);

if ($id === false) {
    // ID is not valid, handle error
} else {
    // Use the sanitized ID in your application
    echo "Dynamic ID: " . $id;
}
