php代码的性能分析。 你可以用xdbug去分析。 但是更好的选择是facebook的性能分析工具xhprof。 它可以图形化。前提是你安装了gd库，你也可能遇到一些小问题。我记得要更新linux的图像库。 安装xhprof扩展:pecl install xhprof . <?php/** * * * Beck Confidential * Copyright (c) 2013, Beck Corp. <Beck.Bi>. * All rights reserved. * * PHP version 5 * * @category Aug * @package package_name * @author beck * @date 2013-8-13 * @license * @link * */ class Xhprof { protected $flags = 0; protected $options = array(); protected $xhprofData = array(); /** * 配置你的xhprof 你可以在php的官网看着个应用的说明 * @param unknown $config * @throws ExtensionNotFoundException */ public function __construct($config = array()) { if (!extension_loaded('xhprof')) { throw new ExtensionNotFoundException( 'Configuration error!
