Function code ($ str, $ ende, $ key = ''){
$ Coded = '';
$ Keylength = strlen ($ key );
$ Str = $ ende = 'decode '? Base64_decode ($ str): $ str;
For ($ I = 0; $ I <strlen ($ str); $ I + = $ keylength ){
$ Coded. = substr ($ str, $ I, $ keylength) ^ $ key;
}
$ Coded = $ ende = 'encoding '? Str_replace ('=', '', base64_encode ($ coded): $ coded;
Return $ coded;
}
We need ENCODE encoding. For DECODE decoding, we only need to set the $ ende parameter.
