How can URL decoding be effectively implemented in PHP?

URL decoding in PHP can be effectively implemented using the built-in function urldecode(). This function takes a URL-encoded string as input and returns the decoded version of the string. To use this function, simply pass the URL-encoded string as an argument to urldecode(). 

$url_encoded_string = "Hello%20World%21";
$decoded_string = urldecode($url_encoded_string);

echo $decoded_string; // Output: Hello World!
