php 性能分析工具 xhprof

php 安装 xhprof 扩展 (兼容php5、7)

git clone git@github.com:longxinH/xhprof.git cd xhprof  /usr/local/php7/bin/phpize  ./configure --with-php-config=/usr/local/php7/bin/php-config  make  sudo make install

扩展编译完成，确定一下

ls /usr/local/php7/lib/php/extensions/no-debug-non-zts-20180731/xhprof.so

把 prepend 文件放在 /tmp/xhprof.prepend.php 下

vi /usr/local/php7/lib/php.ini [xhprof] extension=xhprof.so auto_prepend_file ="/tmp/xhprof.prepend.php";

重启 apache

ps: prepend 文件 xhprof.prepend.php

<?php xhprof_sample_enable(); define('XHPROF_START_TIME', microtime(true)); register_shutdown_function(function () {     $xhprof_time = microtime(true) - XHPROF_START_TIME;     $xhprof_data = xhprof_sample_disable();     if ($xhprof_time > 2 && !empty($xhprof_data)) {         array_unshift($xhprof_data, http_build_query($_REQUEST));         $xhprof_file = '/tmp/xhprof/' . date('YmdHis0000') . uniqid() . '.'             . str_replace('.', '_', strtolower((isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : 'NOHOST')             . '-' . (isset($_SERVER['REQUEST_METHOD']) ? $_SERVER['REQUEST_METHOD'] : 'NOMETHOD')))             . '.xhprof';         file_put_contents($xhprof_file, serialize($xhprof_data));     } });
