大致介绍在这里
==================
Vulcan Logic Disassembler

The Vulcan Logic Disassembler hooks into the Zend Engine and dumps all the opcodes (execution units) of a script. It was written as as a beginning of an encoder, but I never got the time for that. It can be used to see what is going on in the Zend Engine.

New Features in 0.8

PHP 5.0 / PHP 5.1 support.
vld will only show opcodes if the setting vld.active is set to 1.
New Features in 0.6

Class methods info is only dumped if they contain some user defined functions.
Clean up the framework for better opcode display.
Print extended value for function calls (# of args in that case).
Op code elements are only printed when they are actually used.
Download and Installation Instructions
The extension is not totally finished yet, but it works fine for me. If you have questions, feel free to send me an e-mail (but read this first) at derick at php dot net. If you like this piece of software, feel free to checkout my wishlist or Andrei’s. This improves chances that we will be continuing developing VLD.

You can download the source here or get it from CVS. The CVS root is “srmread@cvs.vl-srm.net:/repository”, the module is “vle” (not “vld”) and the password is “srmread”.

It’s not hard to use this extension, but it might not work with all PHP versions. Here are the instructions to get it to work:

Unpack the tarball: tar -xzf vld-0.8.0.tgz.
cd into the newly created directory.
Create the configure script: phpize
Now run “./configure” followed by “make install”.
That’s it, if you now run PHP from the command line and add the -dvld.active=1 parameter VLD will spit out the opcodes:

php -dvld.active=1 program.php

先下载: vld-0.8.0

下载地址 http://www.huanle.net/down/vld.php

执行

#tar -xzf vld-0.8.0.tgz //解压
#mv vld-0.8.0 vld //重命名
#cd -R vld ../php-4.3.8/ext //拷贝vld目录到php的解压目录下的ext中
#cd php-4.3.8
#rm configure //删除configure,因为下面的buildconf会重新生成新的configure
#./buildconf //如果出现错误,就按提示加上相应的参数.
#./configure –with-mysql –with-apxs2=/usr/www/bin/apxs –enable-vld 重新检查php
#make 编译
#make install 安装

服务器必须先安装ZendOptimizer
