How can special characters like "+" be properly handled in PHP when passing them through a URL?

Special characters like "+" in a URL can be properly handled in PHP by using the urlencode() function to encode the special characters before passing them through the URL. This ensures that the special characters are properly interpreted by the server and do not cause any issues. 

$special_char = "+";
$encoded_char = urlencode($special_char);
$url = "http://example.com/page.php?special_char=" . $encoded_char;

// When receiving the URL parameter in PHP, use urldecode() to decode the special characters
$decoded_char = urldecode($_GET['special_char']);
echo $decoded_char; // Output: "+"
