[Transfer] Install PHP performance testing tool xhprof for Windows Apache 2.2 PHP 5.3, performance test xhprof

Original link: http://blog.snsgou.com/post-816 .html

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"

Copy after login

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>";

So you also need to download the graphics tool Graphviz.

4. Download Graphviz

Go here http://www.graphviz.org/Download_windows.php to download the Windows version of Graphviz. I choose to download it here

graphviz-2.38.zip

5. Install Graphviz

After decompression, copy Graphviz to a directory, such as d:/PHP/xhprof/graphviz-2.38/

6. Configure Graphviz

Find the config.php file under the above mentioned website directory /public/xhprof/windows/ and adjust it as follows:

<?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');
