我使用Netbeans的XDebug和Easy XDebug FireFox插件

The add-on is essential when you debug MVC projects, because the normal way XDebug runs in Netbeans is to register the dbug session via the url. With the add-on installed in FireFox, you would set your Netbeans project properties -> Run Configuratuion -> Advanced and select "Do Not Open Web Browser" You can now set your break points and start the debugging session with Ctrl-F5 as usual. Open FireFox and right-click the Add-on icon in the right bottom corner to start monitoring for breakpoints. When the code reaches the breakpoint it will stop and you can inspect your variable states and call-stack.

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。

XDebug对于开发至关重要。我安装它之前任何其他扩展。它为您提供任何错误的堆栈跟踪，您可以轻松地启用分析。

使用var_dump()可以快速查看数据结构。不要使用print_r()，因为你必须用<pre>包围它，而且它一次只打印一个var。

<?php var_dump(__FILE__, __LINE__, $_REQUEST); ?>

对于一个真正的调试环境，我发现最好的是Komodo IDE，但它要花费$$。

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。

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;
        }
    }
}
