最近要做网站的性能对比，于是就找一款性能测试工作来玩玩，工具很多，但相比之前还是觉得xhprof的安装和使用相对来说简单点，数据分析也都还可以，下面就说说它的安装和使用。。。

下载xhprof和graphviz

xhprof的话，直接去php官网就可以下载，为了方便可以戳一下这里
graphviz的话也要下载，主要是显示xhprof性能结果的图形报表，戳这里这里

编译安装xhprof

cd xhprof-0.9.4/xhprof-0.9.4/extension/phpize./configuremakesudo make install

将生成的xhprof.so文件加到php.ini文件中，然后重启apache了

...#这里要使用相对路径加载的话首先要看一下extension_dir配置的路径，或者直接写上`.so`文件的绝对能够路径即可。。。extension=xhprof.so...sudo apachectl restart##测试扩展是否安装成功，有如下输出则okphp --ri xhprof ...    xhprof    xhprof => 0.9.2        CPU num => 4...

安装graphviz

cd graphviz-2.38.0/#后面参数是要确保安装了libphp才行哦【没安装的 brew install linpng 就可】./configure --with-png=yesmakesudo make install

测试一下了

在之前下载的xhprof文件夹里面，找到xhprof_html，xhprof_lib、sample三个文件夹，那这三个文件夹放到你可以访问到得地方去，然后通过连接先访问以下http://xxxx/sample/sample.php，在访问以下http://xxxx/xhprof_html/，就会看到有一条记录，点击后就可以看到分析结果页面，通过点击 View Full CallGraph链接到图形报表的页面。

如何使用

假设你现在要看看看自己做的一个网站的首页性能数据，那么你要找到这个网站的首页入口文件，在核心文件加载之前和之后分别加上xhprof的性能测试代码

#开启，具体参数说明可以查看官方文档xhprof_enable(XHPROF_FLAGS_NO_BUILTINS | XHPROF_FLAGS_CPU | XHPROF_FLAGS_MEMORY);#核心文件的执行...require 'index.php'...#关闭$xhprof_data = xhprof_disable();#这里的路径根据自己的站点来配置$XHPROF_ROOT = realpath(dirname(__FILE__) .'/');include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";$xhprof_runs = new XHProfRuns_Default();$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof");#这里打印出本次测试的id，方便到报表列表页面【http://xxxx/xhprof_html/】去通过对应的id找到对应的结果var_dump($run_id);
