What are the potential issues of passing 255 characters through a URL in PHP?

Passing 255 characters through a URL in PHP can lead to URL encoding issues, as URLs have a maximum length limit. To solve this problem, you can use the base64_encode function to encode the data before passing it through the URL and then decode it on the receiving end. 

// Encode the data before passing it through the URL
$data = "your_long_data_here";
$encoded_data = base64_encode($data);

// Pass the encoded data through the URL
$url = "http://example.com/page.php?data=" . urlencode($encoded_data);

// On the receiving end, decode the data
$received_data = base64_decode($_GET['data']);
