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.

这是我的调试环境:

error_reporting(-1);
assert_options(ASSERT_ACTIVE, 1);
assert_options(ASSERT_WARNING, 0);
assert_options(ASSERT_BAIL, 0);
assert_options(ASSERT_QUIET_EVAL, 0);
assert_options(ASSERT_CALLBACK, 'assert_callcack');
set_error_handler('error_handler');
set_exception_handler('exception_handler');
register_shutdown_function('shutdown_handler');

function assert_callcack($file, $line, $message) {
    throw new Customizable_Exception($message, null, $file, $line);
}

function error_handler($errno, $error, $file, $line, $vars) {
    if ($errno === 0 || ($errno & error_reporting()) === 0) {
        return;
    }

    throw new Customizable_Exception($error, $errno, $file, $line);
}

function exception_handler(Exception $e) {
    // Do what ever!
    echo '<pre>', print_r($e, true), '</pre>';
    exit;
}

function shutdown_handler() {
    try {
        if (null !== $error = error_get_last()) {
            throw new Customizable_Exception($error['message'], $error['type'], $error['file'], $error['line']);
        }
    } catch (Exception $e) {
        exception_handler($e);
    }
}

class Customizable_Exception extends Exception {
    public function __construct($message = null, $code = null, $file = null, $line = null) {
        if ($code === null) {
            parent::__construct($message);
        } else {
            parent::__construct($message, $code);
        }
        if ($file !== null) {
            $this->file = $file;
        }
        if ($line !== null) {
            $this->line = $line;
        }
    }
}

根据问题的不同，我喜欢将error_reporting(E_ALL)与echo测试混合使用(以找到最初发生错误的违规行/文件;你知道它并不总是行/文件php告诉你对吗?)，IDE大括号匹配(解决“解析错误:语法错误，意外的$end”问题)，和print_r();退出;转储(真正的程序员查看源代码;p)。

你也不能用“memory_get_usage();”和“memory_get_peak_usage();”来打败phpdebug(检查sourceforge)来找到问题区域。

如果您不想弄乱输出，输出缓冲是非常有用的。我在一行代码中做到了这一点，我可以随意注释/取消注释

 ob_start();var_dump(); user_error(ob_get_contents()); ob_get_clean();

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。

我使用内置调试器的zend studio for eclipse。与使用eclipse pdt和xdebug进行调试相比，它仍然很慢。希望他们能解决这些问题，在最近的版本中，速度有所提高，但仍然需要2-3秒。 zend firefox工具栏让事情变得非常简单(调试下一页、当前页等)。此外，它还提供了一个分析器，可以对代码进行基准测试，并提供饼状图、执行时间等。
