1. Download XHProf
Go here http://dev.freshsite.pl/php-extensions/xhprof.html to download the Windows version of XHProf. I choose to download it here
XHProf 0.10.3 for PHP 5.3 vc9 and xhprof_html
2. Install XHProf
Copy the xhprof_0.10.3_php53_vc9.dll in the compressed package to the PHP ext directory, and then add the configuration to the php.ini configuration (don’t forget to create the corresponding folder)
[xhprof] extension=xhprof_0.10.3_php53_vc9.dll ; directory used by default implementation of the iXHProfRuns ; interface (namely, the XHProfRuns_Default class) for storing ; XHProf runs. xhprof.output_dir="d:/PHP/xhprof/log"
3. Use XHProf
Extract xhprof_html.zip to the root directory of the website you want to test. For example, I placed it under /public/xhprof/windows in the website directory.
Test file:
<?php function bar($x) { if ($x > 0) { bar($x - 1); } } function foo() { for ($idx = 0; $idx < 5; $idx++) { bar($idx); $x = strlen("abc"); } } // 启动xhprof xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY); // 调用foo函数,也是我们要分析的函数 foo(); // 停止xhprof $xhprof_data = xhprof_disable(); // 取得统计数据 //print_r($xhprof_data); $os = 'windows'; $XHPROF_ROOT = dirname(__FILE__) . '/public/xhprof/' . $os; include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php"; include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php"; // 保存统计数据,生成统计ID和source名称 $xhprof_runs = new XHProfRuns_Default(); $run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_foo"); // source名称是xhprof_foo // 查看统计信息 echo "<div style='margin: 50px auto; padding :10px; width: 92px; font-size: 16px; background: #ff0000;'><a style='color:#ffff00;' href='/public/xhprof/" . $os . "/xhprof_html/index.php?run=" . $run_id . "&source=xhprof_foo' target='_blank'>XHProf view</a></div>";
