xhprof 简单学习试用
使用centos 7 ，使用内置的php 以及结合php-fpm
安装
yum install -y nginx php-fpm xhprof
修改配置添加xhprof支持
- php.ini
安装的位置在/etc/php.ini
[xhprof]
extension=xhprof.so
- nginx 配置

error_log /var/log/nginx/error.log;

include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}

}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
- 测试代码
<?php
xhprof_enable();
// 以下为要分析的代码.
function showSleep($num = 5)
{
$i = 0;
while ($i++ < $num) {
sleep(1);
}
}
function genData($num = 100)
{
$data = [];
$i = 0;
while ($i++ < $num) {
$data[] = $i * $i;
}
sleep(4);
return $data;
}
showSleep(6);
genData(100);
// 以上为要分析的代码.
// 获取分析结果.
$xhprofData = xhprof_disable();
// 引入xhprof_lib.
$xhprofRoot = '/usr/share/xhprof/';
include_once $xhprofRoot . "/xhprof_lib/utils/xhprof_lib.php";
include_once $xhprofRoot . "/xhprof_lib/utils/xhprof_runs.php";
// 保存结果.
$xhprofRuns = new XHProfRuns_Default();
$runId = $xhprofRuns->save_run($xhprofData, "xhprof_show");
// 输出报告地址.
echo 'http://host:port/index.php?run=' . $runId . '&source=xhprof_show';
效果
说明
自己对于php的内部机制不是很了解，以上只是一个简单的记录
