PHP部分代码非我原创，大家可以了解一下这方面的知识

<?php
$date = '8345354023476-3434';
$key = '12345';
$t = new tea ( );
$tea = $t->encrypt ( $date, $key );
$eetea = $t->decrypt ( $tea, $key );
var_dump ( $tea );
var_dump ( $eetea );
class tea {
    private $a, $b, $c, $d;
    private $n_iter;
    public function __construct() {
        $this->setIter ( 32 );
    }
    private function setIter($n_iter) {
        $this->n_iter = $n_iter;
