常用的js方法封装,PHP加密由javascript解密的例子

PHP加密函数

暂时只封装了这些方法,有待提升,如有不对的地方  多谢指正

 代码如下

/*

<?php
 
function strencode($string) {
    $string = base64_encode($string);
    $key = md5(‘just a test’);
    $len = strlen($key);
    $code = ”;
    for ($i = 0; $i < strlen($string); $i++) {
        $k = $i % $len;
        $code .= $string [$i] ^ $key [$k];
    }
    return base64_encode($code);
}
 
echo strencode(‘just a test’);
?>
