定位PHP文件编码Zend Guard


Locating PHP Files Encoded with Zend Guard

是否有一种方法可以在使用Zend Guard编码的源代码树中找到PHP文件?

有关于尝试解码zend编码文件的现有问题,但我继承了一个大型PHP应用程序,必须在某个远程库的某个地方使用zend编码的文件,因为我一直在我的应用程序的错误日志中得到以下输出:

<h2>What is the Zend Optimizer?</h2>
<p>The Zend Optimizer is one of the most popular PHP plugins 
for performance-improvement, and has been available without 
charge, since the early days of PHP 4. It improves performance 
by scanning PHP's intermediate code and passing it through 
multiple Optimization Passes to replace inefficient code 
patterns with more efficient code blocks. The replaced code 
blocks perform exactly the same operations as the original 
code, only faster. </p>
<p>In addition to improving performance, the Zend Optimizer 
also enables PHP to transparently load files encoded by the 
Zend Guard. </p>
<p>The Zend Optimizer is a free product available for download 
from <a href="http://www.zend.com">Zend Technologies</a>. 
Zend Technologies also developed the PHP scripting engine, 
known as the <a href="http://www.zend.com/products/zend_engine">Zend Engine</a>.</p>

我有没有的想法,这个文件是在应用程序!我无法找到关于Zend Guard编码的文件特征的任何信息,因此我不知道在文件系统中搜索什么。谷歌一直没有提供帮助。"userscape"、"helpspot"(显然是userscape的产品)甚至"zend"的简单grep显示为空白。

编辑:然而,根据FAQ Zend Guard使用公钥加密,所以我相当肯定这些文件无论如何都不会有任何可识别的PHP代码。


是否有一种通用的方法来定位文件系统中Zend guard编码的PHP文件?是否存在可搜索的文件的共同属性?

我相信大多数Zend Optimizer编码的文件将以类似于

的头开始:
<?php @Zend;

它们还将包含您在错误消息中看到的所有文本,包括单词"Zend Optimizer"。你可以搜索一下。:)
