For a long time, I have used a small plug-in written by myself for PHP debugging and running performance monitoring, and I feel that it is okay. But when I was browsing around just now, I found something called Xhprof. After a brief look at the introduction, it seemed to be similar to my little plug-in. I would like to sort out the applications of Xhprof and compare it with my plug-in.

Application 1

<code><span><span><?php</span>
xhprof_enable();
【PHP业务代码】
<span>$data</span> = xhprof_disable();
<span>// xhprof_lib在下载的包里存在这个目录,记得将目录包含到运行的php代码中</span><span>include_once</span><span>"xhprof_lib/utils/xhprof_lib.php"</span>;  
<span>include_once</span><span>"xhprof_lib/utils/xhprof_runs.php"</span>;  

<span>$objXhprofRun</span> = <span>new</span> XHProfRuns_Default(); 

<span>// 第一个参数j是xhprof_disable()函数返回的运行信息</span><span>// 第二个参数是自定义的命名空间字符串(任意字符串),</span><span>// 返回运行ID,用这个ID查看相关的运行结果</span><span>$run_id</span> = <span>$objXhprofRun</span>->save_run(<span>$data</span>, <span>"xhprof"</span>);
var_dump(<span>$run_id</span>);</span></span></code>

Application 2

<code><span><span><?php</span><span>//cpu:XHPROF_FLAGS_CPU 内存:XHPROF_FLAGS_MEMORY，这两个都是整形常量，可以相加</span>
xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);
【PHP业务代码】
<span>$data</span> = xhprof_disable();
</span></code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced the Xhprof application, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
