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.soauto_prepend_file ="/tmp/xhprof.prepend.php";

重启 apache

ps: prepend 文件 xhprof.prepend.php

<?phpxhprof_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));    }});
