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.

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。

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。

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;
        }
    }
}

当不能使用Rails时，我经常使用CakePHP。为了调试错误，我通常会在tmp文件夹中找到error.log，然后在终端中使用命令…

tail -f app/tmp/logs/error.log

它可以让你从蛋糕中运行正在发生的事情的对话框，这非常方便，如果你想在代码中输出一些东西，你可以使用。

$this->log('xxxx');

这通常可以让你很好地了解发生了什么。

Print_r (debug_backtrace());

或者类似的东西:-)
