title: PHP URL Encoding / Decoding
body: <p>I used the solution accepted for this <a href="https://stackoverflow.com/questions/1289061/best-way-to-use-php-to-encrypt-and-decrypt">question</a> for encrypting by id for example in <strong>/index.php?id=3</strong> . The problem is I cannot send the encrypted value as an url, example <strong>/index.php?id=dsf13f3343f23/23=</strong>. Because sometimes it will have weird characters in the url e.g. notice the <code>=</code> sign in the end </p>
