这篇文章主要为大家详细介绍了PHP二进制加密与解密的简单示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随php教程的小玲来看看吧！

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。

代码如下:

<code><?php
/*   php教程 www.512Pic.com   */
   
 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,'<?php
/*   php教程 www.512Pic.com   */
');  
         $footerPos = strrpos($contents,'?>');  
         $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);  
         $encode = base64_encode(gzdeflate($contents)); // 开始编码  
         $encode = '<?php
/*   php教程 www.512Pic.com   */
'."\n eval(gzinflate(base64_decode("."'".$encode."'".")));\n\n?>";   
 
         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！"
 ?> 
</code>

加密方式2：

代码如下:

<code><?php
/*   php教程 www.512Pic.com   */
   
 
 function RandAbc($length = "") { // 返回随机字符串  
     $str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";  
     return str_shuffle($str);  
 }   
 
 $filename = 'index.php'; //要加密的文件  
 $T_k1 = RandAbc(); //随机密匙1  
 $T_k2 = RandAbc(); //随机密匙2  
 $vstr = file_get_contents($filename);  
 $v1 = base64_encode($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";  
 $q2 = "O0O000";  
 $q3 = "O0OO00";  
 $q4 = "OO0O00";  
 $q5 = "OO0000";  
 $q6 = "O00OO0";  
 $s = '$'.$q6.'=urldecode("%6E1%7A%62%2F%6D%615%5C%76%740%6928%2D%70%78%75%71%79%2A6%6C%72%6B%64%679%5F%65%68%63%73%77%6F4%2B%6637%6A");$'.$q1.'=$'.$q6.'{3}.$'.$q6.'{6}.$'.$q6.'{33}.$'.$q6.'{30};$'.$q3.'=$'.$q6.'{33}.$'.$q6.'{10}.$'.$q6.'{24}.$'.$q6.'{10}.$'.$q6.'{24};$'.$q4.'=$'.$q3.'{0}.$'.$q6.'{18}.$'.$q6.'{3}.$'.$q3.'{0}.$'.$q3.'{1}.$'.$q6.'{24};$'.$q5.'=$'.$q6.'{7}.$'.$q6.'{13};$'.$q1.'.=$'.$q6.'{22}.$'.$q6.'{36}.$'.$q6.'{29}.$'.$q6.'{26}.$'.$q6.'{30}.$'.$q6.'{32}.$'.$q6.'{35}.$'.$q6.'{26}.$'.$q6.'{30};eval($'.$q1.'("'.base64_encode('$'.$q2.'="'.$c.'";eval(\'?>\'.$'.$q1.'($'.$q3.'($'.$q4.'($'.$q2.',$'.$q5.'*2),$'.$q4.'($'.$q2.',$'.$q5.',$'.$q5.'),$'.$q4.'($'.$q2.',0,$'.$q5.'))));').'"));';  
 
 $s = '<?php
/*   php教程 www.512Pic.com   */
 '."\n".$s."\n".' ?>';  
 //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');  
 
 ?> 
</code>

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：

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");
