How can the rawurlencode() and rawurldecode() functions be leveraged for maintaining string integrity in PHP scripts?

When passing strings with special characters in URLs in PHP scripts, it is important to use rawurlencode() to encode the string before passing it in the URL and then use rawurldecode() to decode it back to its original form. This ensures that the string maintains its integrity and special characters are properly handled. 

// Encoding a string before passing it in a URL
$string = "Hello, World!";
$encodedString = rawurlencode($string);
$url = "https://example.com?data=" . $encodedString;

// Decoding the string back to its original form
$decodedString = rawurldecode($encodedString);
echo $decodedString; // Output: Hello, World!
