How can special characters in encrypted strings be properly encoded for URL transmission in PHP?

Special characters in encrypted strings need to be properly encoded for URL transmission in PHP to ensure that the data is transmitted correctly and securely. One way to do this is by using the urlencode() function in PHP to encode the encrypted string before sending it in the URL. 

$encryptedString = "encrypted_data_here";
$encodedString = urlencode($encryptedString);

// Transmit the encoded string in the URL
echo "https://example.com/?data=" . $encodedString;
