以下函数代码中“123456” 是个加密的key,自己可以随便改。
php加密,js解密,貌似没什么意义,主要是key在js中会被看到。
不过在某些地方可能会用到。

PHP加密函数

复制代码 代码如下:
 function strencode($string) {  
    $string = base64_encode ( $string );  
    $key = md5 ( '123456' );  
    $len = strlen ( $key ); 
    $code = '';  
    for($i = 0; $i  $k = $i % $len;      
 $code .= $string [$i] ^ $key [$k];  
    }  
    return base64_encode ( $code );  
}  
echo strencode ( 'abced你好我是你们定的点点滴滴asd@#$)()*&*&*' );  
?> 

js解密函数:

复制代码 代码如下:
<script> <BR>function strencode(string) { <BR>key = calcMD5('123456'); <BR>string = Base64.decode(string); <BR> len = key.length; <BR> code = ''; <BR> for (i = 0; i < string.length; i++) { <BR> k = i % len; <BR> code += String.fromCharCode(string.charCodeAt(i) ^ key.charCodeAt(k)); <BR> } <BR> return Base64.decode(code); <BR>}<BR>alert(strencode('PGZ6Cz40Z1JCWCYNRVtSDwsvfVsIexpcEFN0DU0OSQkXQUIPCQxnV1NLDA9SSw8PF1JhWxAHZ18FAGIncUFiFS5yWxAuClxUf15fXA==')); <BR></script> 

PHP 加密 & JS 解密2

复制代码 代码如下:
if(!function_exists(jm))
{
    function jm($str){
  $len = strlen($str);
  for($i=0;$i  {
   $ascc=ord($str[$i]);
   if($ascc   {
    $ascc=$ascc^7;
   }
   $res.=chr($ascc);
  }
  return $res;
    }//end function
}
echo "<script><BR>xflag=true;<BR>function xcount(xh){<BR> if(!xflag) return;<BR> var xc=\"\",xd=new Array(),xe=\"\",xf=0;<BR> for(i=0;i<xh.length;i++){<BR> xa=xh.charCodeAt(i);<BR> if(xa<128)xa=xa^7;<BR> xe+=String.fromCharCode(xa);<BR> if(xe.length>80){<BR> xd[xf++]=xe;xe=\"\";<BR> }<BR> }<BR> xc=xd.join(\"\")+xe;<BR> document.write(xc);<BR>}</script>";
$check_count = addslashes(jm("<script>alert('测试咯~~~');</script>"));
$check_count="";
echo "$check_count";
echo "";
