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.

通过简单地var_dump一些关键变量，可以很容易地找到大多数错误，但这显然取决于您开发的应用程序类型。

对于更复杂的算法，步进/断点/观察函数是非常有用的(如果没有必要)

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;
        }
    }
}

PhpEdit有一个内置调试器，但我通常最终使用echo();和print_r ();老式的方式!!

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。

在生产环境中，我使用error_log()将相关数据记录到服务器的错误日志中。
