分享2种PHP的源码加密方式，此加密方法支持任意PHP版。

注意，加密后的PHP代码无需第三方工具解密，像往常一样，直接运行即可。

复制代码代码如下:

function encode_file_contents($filename) {
     $type=strtolower(substr(strrchr($filename,'.'),1));
     if ('php' == $type && is_file($filename) && is_writable($filename)) { // 如果是PHP文件并且可写则进行压缩编码
         $contents = file_get_contents($filename); // 判断文件是否已经被编码处理
         $contents = php_strip_whitespace($filename);

         // 去除PHP头部和尾部标识
         $headerPos = strpos($contents,'         $footerPos = strrpos($contents,'?>');
         $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);
         $encode = base64_encode(gzdeflate($contents)); // 开始编码
         $encode = '";

         return file_put_contents($filename, $encode);
     }
     return false;
}

//调用函数
$filename = 'dam.php';
encode_file_contents($filename);
echo "OK,加密完成！"
?>

加密方式2：

复制代码代码如下:

其实，PHP加密源码方式有很多，譬如，免费的微盾PHP加密，还有 www.phpjm.net 搞的在线加密，只是phpjm更复杂点而已。

另外，分享一个 PHP类，它能对文本的内容进行二进制加密与解密，代码如下：

复制代码代码如下:

class text_auth
{
     var $n_iter;

     function text_auth()
     {
         $this->setIter(32);
     }

     function setIter($n_iter)
     {
         $this->n_iter = $n_iter;
     }

     function getIter()
     {
         return $this->n_iter;
     }

     function encrypt($data, $key)
     {
         $n = $this->_resize($data, 4);

         $data_long[0]   = $n;
         $n_data_long    = $this->_str2long(1, $data, $data_long);

         $n = count($data_long);
         if (($n & 1) == 1) {
             $data_long[$n] = chr(0);
             $n_data_long++;
         }

         $this->_resize($key, 16, true);
         if ( '' == $key )
             $key = '0000000000000000';

         $n_key_long = $this->_str2long(0, $key, $key_long);

         $enc_data   = '';

         for ($i = 0; $i              if ($j + 4                  $k[0] = $key_long[$j];
                 $k[1] = $key_long[$j + 1];
                 $k[2] = $key_long[$j + 2];
                 $k[3] = $key_long[$j + 3];
             } else {
                 $k[0] = $key_long[$j % $n_key_long];
                 $k[1] = $key_long[($j + 1) % $n_key_long];
                 $k[2] = $key_long[($j + 2) % $n_key_long];
                 $k[3] = $key_long[($j + 3) % $n_key_long];
             }
             $j = ($j + 4) % $n_key_long;

             $this->_encipherLong($data_long[$i], $data_long[++$i], $w, $k);

使用方法参考如下：
// 加密过程
view sourceprint?
$text_file = S_ROOT . './456.php';
$str = @file_get_contents($text_file);

require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);

$str = $text_auth->encrypt($str, "qianyunlai.com");

$filename = S_ROOT . './789.php'; // 加密后的文本为二进制，普通的文本编辑器无法正常查看
file_put_contents($filename, $str);
// 解密过程
view sourceprint
?01 $text_file = S_ROOT . './789.php';
$str = @file_get_contents($text_file);

require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);

$str = $text_auth->decrypt($str, "qianyunlai.com");

$filename = S_ROOT . './456.php';
file_put_contents($filename, $str);
