Xhprof Application-PHP Tutorial-php.cn

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

 xhprof_enable(); 【PHP业务代码】 $data = xhprof_disable(); // 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include_once"xhprof_lib/utils/xhprof_lib.php"; include_once"xhprof_lib/utils/xhprof_runs.php"; $objXhprofRun = new XHProfRuns_Default(); // 第一个参数j是xhprof_disable()函数返回的运行信息// 第二个参数是自定义的命名空间字符串(任意字符串),// 返回运行ID,用这个ID查看相关的运行结果$run_id = $objXhprofRun->save_run($data, "xhprof"); var_dump($run_id);

Application 2

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

').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.
