What is the method to decode php urlencode?

In PHP, you can decode URLs by using the urldecode function. Here is the specific usage method:

<?php
$url = "http%3A%2F%2Fwww.example.com%2Fpage.php%3Fname%3DJohn%26age%3D25";

$decodedUrl = urldecode($url);

echo $decodedUrl;
?>

The output result is:

http://www.example.com/page.php?name=John&age=25

The urldecode function decodes special characters in a URL into their original characters.
