1)使用print_r()。在TextMate中，我有一个'pre'的片段，它扩展为:

echo "<pre>";
print_r();
echo "</pre>";

2)我使用Xdebug，但还不能让GUI在我的Mac上正常工作。它至少打印出一个可读的堆栈跟踪版本。

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.

print_r() +1。使用它来转储对象或变量的内容。为了使它更具可读性，使用pre标记，这样你就不需要查看源代码了。

echo '<pre>';
print_r($arrayOrObject);

还有var_dump($thing) -这对于查看子事物的类型非常有用

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.

Print_r (debug_backtrace());

或者类似的东西:-)
