php installs threads multi-threading extension, phpthreads multi-threading

php5.3 or above, and it is a thread-safe version. The compilers used by apache and php must be consistent.
If Thread Safety is enabled through phpinfo(), it means the thread-safe version.
You can know the compiler used by viewing the Compiler item through phpinfo(). Mine is: MSVC9 (Visual C 2008).

1. Download the pthreads extension
Download address: http://windows.php.net/downloads/pecl/releases/pthreads

2. Install pthreads extension
Copy php_pthreads.dll to the directory binphpext.
Copy pthreadVC2.dll to the directory binphp.
Copy pthreadVC2.dll to the directory C:windowssystem32.
Open the php configuration file php.ini. Add extension=php_pthreads.dll
prompt at the end! Windows systems need to add the path of pthreadVC2.dll to the PATH environment variable. My Computer--->right mouse button--->Properties--->Advanced--->Environment Variables--->System Variables--->Find the path named Path---> ;Edit--->Add the full path of pthreadVC2.dll at the end of the variable value (mine is C:WINDOWSsystem32pthreadVC2.dll).

3. Add thread class

<?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 />

4. Test pthreads extension

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 />
