我使用Netbeans的XDebug和Easy XDebug FireFox插件

The add-on is essential when you debug MVC projects, because the normal way XDebug runs in Netbeans is to register the dbug session via the url. With the add-on installed in FireFox, you would set your Netbeans project properties -> Run Configuratuion -> Advanced and select "Do Not Open Web Browser" You can now set your break points and start the debugging session with Ctrl-F5 as usual. Open FireFox and right-click the Add-on icon in the right bottom corner to start monitoring for breakpoints. When the code reaches the breakpoint it will stop and you can inspect your variable states and call-stack.

XDebug对于开发至关重要。我安装它之前任何其他扩展。它为您提供任何错误的堆栈跟踪，您可以轻松地启用分析。

使用var_dump()可以快速查看数据结构。不要使用print_r()，因为你必须用<pre>包围它，而且它一次只打印一个var。

<?php var_dump(__FILE__, __LINE__, $_REQUEST); ?>

对于一个真正的调试环境，我发现最好的是Komodo IDE，但它要花费$$。

PhpEdit有一个内置调试器，但我通常最终使用echo();和print_r ();老式的方式!!

集成的调试器，可以在逐步执行代码时观察变量值的变化，这真的很酷。但是，它们确实需要在服务器上安装软件，并在客户机上进行一定数量的配置。两者都需要定期维护以保持良好的工作状态。

print_r易于编写，并保证在任何设置中都能工作。

Nusphere也是一个很好的php调试器 nusphere
