/**
 * @ string $str 要编码的字符串
 * @ string $ende 操作ENCODE编码,DECODE解码
 * @ string $key hash值
 * @return string
 */
function code($str, $ende, $key = '') {
 $coded = '';
 $keylength = strlen($key);
 $str = $ende == 'DECODE' ? base64_decode($str) : $str;
 for($i = 0; $i   $coded .= substr($str, $i, $keylength) ^ $key;
 }
 $coded = $ende == 'ENCODE' ? str_replace('=', '', base64_encode($coded)) : $coded;
 return $coded;
}
我要们要 ENCODE编码,DECODE解码 只要设置$ende的参数就行了。
