手动调试对我来说通常更快——var_dump()和debug_print_backtrace()是你需要用来武装你的逻辑的所有工具。

我使用了Zend Studio(5.5)和Zend平台。这就提供了适当的调试、断点/跨代码等，尽管是有代价的。

Komodo IDE works well with xdebug, even for the remore debugging. It needs minimum amount of configuration. All you need is a version of php that Komodo can use locally to step through the code on a breakpoint. If you have the script imported into komodo project, then you can set breakpoints with a mouse-click just how you would set it inside eclipse for debugging a java program. Remote debugging is obviously more tricky to get it to work correctly ( you might have to map the remote url with a php script in your workspace ) than a local debugging setup which is pretty easy to configure if you are on a MAC or a linux desktop.

Xdebug和用于notepad++的DBGp插件用于繁重的bug查找，FirePHP用于轻量级的东西。又快又脏?没有什么比dBug更好的了。

Nusphere也是一个很好的php调试器 nusphere

有许多PHP调试技术可以在编码时节省无数的时间。一个有效但基本的调试技术是简单地打开错误报告。另一种稍微高级一点的技术涉及到使用print语句，它可以通过在屏幕上显示实际发生的内容来帮助查明更难以捉摸的错误。PHPeclipse是一个Eclipse插件，可以突出显示常见的语法错误，并且可以与调试器一起使用来设置断点。

display_errors = Off
error_reporting = E_ALL 
display_errors = On

也用过

error_log();
console_log();
