Install PHP performance testing tool xhprof for Windows + Apache 22 + PHP 53

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 XHProf, I choose to download

XHProf 0.10.3 for PHP 5.3 vc9 and xhprof_html

2. Install XHProf

and copy the xhprof_0.10.3_php53_vc9.dll in the compressed package to the ext directory of PHP, and then in php Add the configuration to the .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

to unzip xhprof_html.zip to the root directory of the website you want to test, for example, I placed it in the website directory / Under public/xhprof/windows.

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;
<strong>include</strong>_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
<strong>include</strong>_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><a href='/public/xhprof/" . $os . "/xhprof_html/index.php?run=" . $run_id . "&source=xhprof_foo' target='_blank'>XHProf view</a></div>";

When clicking the link "[View Full Callgraph]", an error will be reported:

failed to execute cmd: " dot -Tpng"

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

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 under the above mentioned website directory /public/xhprof/windows/ file, adjusted 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');

Re-click the link [View Full Callgraph], and a long-awaited rendering comes out:

The above introduces the installation of the PHP performance testing tool xhprof for Windows + Apache 22 + PHP 53, including the include content. I hope it will be helpful to friends who are interested in PHP tutorials.
