How can PHP be used to decode and encode URLs effectively in a website?

To decode and encode URLs effectively in a website using PHP, you can use the built-in functions `urlencode()` to encode URLs and `urldecode()` to decode them. This is useful when passing data through URLs or working with query strings. These functions ensure that special characters are properly encoded or decoded, preventing any issues with the URL structure. 

// Encode a URL
$url = "https://www.example.com/page.php?name=John Doe";
$encoded_url = urlencode($url);

// Decode a URL
$decoded_url = urldecode($encoded_url);

echo "Encoded URL: " . $encoded_url . "<br>";
echo "Decoded URL: " . $decoded_url;
