通常我发现创建一个自定义日志功能可以保存在文件中，存储调试信息，并最终在公共页脚上重新打印。

您还可以重写常见的Exception类，以便这种类型的调试是半自动化的。

集成的调试器，可以在逐步执行代码时观察变量值的变化，这真的很酷。但是，它们确实需要在服务器上安装软件，并在客户机上进行一定数量的配置。两者都需要定期维护以保持良好的工作状态。

print_r易于编写，并保证在任何设置中都能工作。

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。

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;
        }
    }
}

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。
