How can rawurlencode() be used to prevent issues with passing strings in PHP URLs?

When passing strings in PHP URLs, special characters like spaces, ampersands, and other symbols can cause issues. To prevent problems, you can use the rawurlencode() function in PHP to encode the string before passing it in the URL. This function converts special characters into a format that can be safely passed in a URL. 

$string = "Hello World!";
$encodedString = rawurlencode($string);
$url = "example.php?data=" . $encodedString;

// In example.php, use rawurldecode() to decode the string
$decodedString = rawurldecode($_GET['data']);
echo $decodedString; // Output: Hello World!
