1、下载XHPRof

到这里 http://dev.freshsite.pl/php-extensions/xhprof.html 下载Windows版本的XHProf,我这里选择下载

XHProf 0.10.3 for PHP 5.3 vc9 和 xhprof_html

 

2、安装XHProf

把压缩包里的 xhprof_0.10.3_php53_vc9.dll 拷贝到PHP的ext目录下,然后在php.ini配置里面加入配置(不要忘记创建对应的文件夹)

[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、使用XHProf

 xhprof_html.zip 解压到你想测试的网站根目录,如我放在了网站目录的 /public/xhprof/windows 下。

测试文件:

<?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>";

  

当点击链接“[View Full Callgraph]”时,会报错:

failed to execute cmd: " dot -Tpng"

所以还需要下载图形工具 Graphviz

 

 

4、下载Graphviz

到这里 http://www.graphviz.org/Download_windows.php 下载Windows版本的Graphviz,我这里选择下载  

graphviz-2.38.zip

 

5、安装Graphviz

解压后,把Graphviz拷贝到某个目录,如 d:/PHP/xhprof/graphviz-2.38/

 

6、配置Graphviz

找到上述提到网站目录 /public/xhprof/windows/ 下的 config.php 文件,调整如下:

<?php
/**
 * Set the absolute paths on your system
 */
define('ERROR_FILE', 'd:/PHP/xhprof/log/xhprof_dot_errfile.log');
define('TMP_DIRECTORY', 'd:/PHP/xhprof/tmp');
define('DOT_BINARY', 'd:/PHP/xhprof/graphviz-2.38/release/bin/dot.exe');

  重新点击链接 [View Full Callgraph],一张期待已久的效果图出来啦:
