PHP调试有很多中方法。今天给大家推荐的是 FirePHP(http://www.firephp.org/)。

这个工具,是基于firefox的一个组件。Firephp组件安装地址。使用之前需要先安装下这个组件。完了还需要down一个FirePHP的包。下载地址

下载完成后可以看到包里的文件如下:

我们现在来写个例子测试下。(需要include 进来fb.php文件哦)代码如下:

我们在firefox下运行。结果如下:
firephp - 3

在这里就可以看到$str的值了。

接下来来介绍下FirePHP的几个常用方法:

1、  fb($para) 该方法就是如上示例。可以监测某个变量的值。该方法等同于FB::log($para)。

2、  FB:: info ($str);   该方法和fb()方法类似。不同的地方在于其运行结果在firefox中会有个不同的标志。(见图三)

3、  FB::warn($str);   同上类似。

4、  FB::error($str);   同上类似。


图三

5、  FB::trace($str); 该方法用于监控变量的调用栈。如下图示例。

我们也可以在类中使用FB。如下示例:

运行结果如下:
firephp

在fb.php中,我们可以看到有如下多的方法,在这里就不一一介绍了。主要常用的就是上面五个。有兴趣的同学可以仔细去研究测试下其他方法。
