How can one prevent PHP parse errors while using preg_replace with callback functions?

When using preg_replace with callback functions in PHP, it is important to handle potential parse errors by wrapping the callback function in a try-catch block. This will allow you to catch any errors that may occur during the callback execution and prevent them from causing the script to stop running. 

try {
    $result = preg_replace_callback('/pattern/', function($matches) {
        // callback logic here
    }, $input);
} catch (Exception $e) {
    // handle the error gracefully
    echo "An error occurred: " . $e->getMessage();
}
