有没有一种方法可以在使用Zend Guard编码的源代码树中查找PHP文件？查找使用Zend Guard编码的PHP文件
有existingquestions约试图解码的Zend编码的文件，但我继承必须某处在一些偏远的图书馆，因为我不断收到在我的应用程序下面的输出使用Zend的编码文件的大型PHP应用程序错误日志：

<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>

我没有知道哪里该文件是在应用程序！我一直无法找到Zend Guard编码的文件的特征信息，所以我不知道该如何搜索文件系统。 Google一直没有帮助。简单grep s为“userscape”“helpspot”（显然是UserScape的产品），甚至“zend”空白。
编辑：但是，根据the FAQ Zend Guard使用public key crypto，所以我相当肯定这些文件无论如何不会有任何可识别的PHP代码。
有没有找到文件系统中的Zend的卫队编码的PHP文件通用方式？有可搜索文件的常见属性吗？
不知道它是如何混淆文件，我不能确定，但我会建议greaps的东西，如'eval'，'preg_replace/e'和'base64_decode' – andrewsi
好的想法，不幸的' eval'只返回一大堆[SimpleTest]（http://www.simpletest.org/）和Javascript命中。 – beporter
你和其他人有什么关系吗？你也可以做一些像'grep -r eval * | grep php'递归查找包含'eval'的文件，然后grep php的结果 - 这可能有助于跳过javascript。 – andrewsi
