PHP源码加密方法实例详解

php源码加密方法实例

下面我们来介绍一下使用PHP加密源码的方法和效果。

?phpfunction Randabc($length=""){
    //返回随机字符串    $str="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
      return str_shuffle($str);
  }
      $filename='index.php';
      $T_k1=RandAbc();
    //随机密匙1  $T_k2=RandAbc();
    //随机密匙2  $vstr=file_get_contents($filename);
    //要加密的文件  $v1=base64_encode($vstr);
      $c=strtr($v1,$T_k1,$T_k2);
    //根据密匙替换对应字符。  $c=$T_k1.$T_k2.$c;
      $q1="O00O0O";

    ').'"));
    ';
     $s='?'.$s.' ?>
    ';
     echo $s;
    //生成 加密后的PHP文件$fpp1 = foPEn('temp'.$filename,'w');
    fwrITe($fpp1,$s) or die('写文件错误');
     ?>
    

效果：
