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.

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。

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;
        }
    }
}

PhpEd真的很好。你可以进入/进入/退出函数。你可以运行特别代码，检查变量，改变变量。太神奇了。

坦率地说，是print和print_r()的组合，以打印出变量。我知道很多人更喜欢使用其他更高级的方法，但我发现这是最容易使用的。

我要说的是，直到我在Uni做了一些微处理器编程，甚至都不会使用它，我才完全理解这一点。

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。
