What alternative PHP function can be used to handle special characters like '&' in URL parameters?

When passing URL parameters in PHP, special characters like '&' can cause issues as they are reserved characters in URLs. To handle special characters like '&' in URL parameters, you can use the `urlencode()` function in PHP. This function encodes the string so that it can be safely used in a URL without causing any conflicts. 

// Encode the URL parameter using urlencode() function
$encoded_parameter = urlencode($parameter_value);

// Include the encoded parameter in the URL
$url = "http://example.com/page.php?param=" . $encoded_parameter;

// Retrieve the encoded parameter from the URL and decode it using urldecode()
$decoded_parameter = urldecode($_GET['param']);
