php安装threads多线程扩展,phpthreads多线程

php5.3或以上,且为线程安全版本。apache和php使用的编译器必须一致。
通过phpinfo()查看Thread Safety为enabled则为线程安全版。
通过phpinfo()查看Compiler项可以知道使用的编译器。本人的为:MSVC9 (Visual C++ 2008)。

 

一、下载pthreads扩展
下载地址:http://windows.php.net/downloads/pecl/releases/pthreads

 

二、安装pthreads扩展
复制php_pthreads.dll 到目录 bin\php\ext\ 下面。
复制pthreadVC2.dll 到目录 bin\php\ 下面。
复制pthreadVC2.dll 到目录 C:\windows\system32 下面。
打开php配置文件php.ini。在后面加上extension=php_pthreads.dll
提示!Windows系统需要将 pthreadVC2.dll 所在路径加入到 PATH 环境变量中。我的电脑--->鼠标右键--->属性--->高级--->环境变量--->系统变量--->找到名称为Path的--->编辑--->在变量值最后面加上pthreadVC2.dll的完整路径(本人的为C:\WINDOWS\system32\pthreadVC2.dll)。

 

三、添加thread类

<?php<br />class Thread<br />{<br /><br />    var $hooks = array();<br />    var $args = array();<br /><br />    function thread()<br />    {<br /><br />    }<br /><br />    function addthread($func)<br />    {<br />        $args = array_slice(func_get_args(), 1);<br />        $this->hooks[] = $func;<br />        $this->args[] = $args;<br />        return true;<br />    }<br /><br />    function runthread()<br />    {<br />        if(isset($_GET['flag']))<br />        {<br />            $flag = intval($_GET['flag']);<br />        }<br />        if($flag || $flag === 0)<br />        {<br />            call_user_func_array($this->hooks[$flag], $this->args[$flag]);<br />        }<br />        else<br />        {<br />            for($i = 0, $size = count($this->hooks); $i < $size; $i++)<br />            {<br />                $fp=fsockopen($_SERVER['HTTP_HOST'],$_SERVER['SERVER_PORT']);<br />                if($fp)<br />                {<br />                    $out = "GET {$_SERVER['PHP_SELF']}?flag=$i HTTP/1.1rn";<br />                    $out .= "Host: {$_SERVER['HTTP_HOST']}rn";<br />                    $out .= "Connection: Closernrn";<br />                    fputs($fp,$out);<br />                    fclose($fp);<br />                }<br />            }<br />        }<br />    }<br />}<br /><br /><br />

四、测试pthreads扩展

include('thread.php');<br />class AsyncOperation extends Thread {<br />    public function __construct($arg){<br />        $this->arg = $arg;<br />    }<br /><br />    public function run(){<br />        if($this->arg){<br />            printf("Hello %s\n", $this->arg);<br />        }<br />    }<br />}<br />$thread = new AsyncOperation("World");<br />if($thread->start())<br />    $thread->join();<br /><br /><br />
