尝试Eclipse PDT来设置具有您提到的调试特性的Eclipse环境。与var_dump的老方法相比，进入代码的能力是一种更好的调试方法，并在各个点打印，以查看流在哪里出错。当所有这些都失败了，虽然，我只有SSH和vim，我仍然var_dump()/die()找到哪里的代码出错。

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。

您可以使用Firephp作为firebug的附加组件在与javascript相同的环境中调试php。

我还使用前面提到的Xdebug来分析php。

For the really gritty problems that would be too time consuming to use print_r/echo to figure out I use my IDE's (PhpEd) debugging feature. Unlike other IDEs I've used, PhpEd requires pretty much no setup. the only reason I don't use it for any problems I encounter is that it's painfully slow. I'm not sure that slowness is specific to PhpEd or any php debugger. PhpEd is not free but I believe it uses one of the open-source debuggers (like XDebug previously mentioned) anyway. The benefit with PhpEd, again, is that it requires no setup which I have found really pretty tedious in the past.

Nusphere也是一个很好的php调试器 nusphere

由Derick Rethans编写的Xdebug非常好。我前段时间用过，发现安装起来不那么容易。一旦你完成了，你就不会明白没有它你是如何做到的:-)

在Zend开发者专区有一篇很好的文章(在Linux上安装似乎并不容易)，甚至还有一个Firefox插件，我从来没用过。
