Windows install PHP Real multi-threaded extension pthreads tutorial

Extension Address: http://docs.php.net/manual/zh/book.pthreads.php

Precautions
php5.3 or more, and is a thread-safe version. The compilers used by Apache and PHP must be consistent.
Thread-safe version is phpinfo () to view thread safety as enabled.
You can see the compiler that is used by phpinfo () to view the compiler item. my: MSVC9 (Visual C + + 2008).


I use the environment
32-bit Windows XP Sp3,wampserver2.2d (PHP5.3.10-VC9 + apache2.2.21-vc9).


First, download pthreads extension
: Http://windows.php.net/downloads/pecl/releases/pthreads
According to my environment, I downloaded the pthreads-2.0.8-5.3-ts-vc9-x86.
2.0.8 represents the version of Pthreads.
5.3 Represents the version of PHP.
TS indicates that PHP wants a thread-safe version.
Vc9 means that PHP is compiled by the Visual C + + 2008 compiler.
The x86 represents a 32-bit


Second, install pthreads extension
Copy the Php_pthreads.dll to the directory bin\php\ext\ below. (I path D:\wamp\bin\php\php5.3.10\ext)
Copy the PthreadVC2.dll to the directory bin\php\ below. (I path D:\wamp\bin\php\php5.3.10)
Copy the PthreadVC2.dll to the directory C:\windows\system32 below.
Open php config file php.ini. Add Extension=php_pthreads.dll to the back.
Tips! The Windows system needs to include the path of the PthreadVC2.dll into the PATH environment variable. My Computer---> Right---> Properties---> Advanced---> Environment variables---> System variables---> Find---> Edit---> Named path At the end of the variable value, add the full path to the PthreadVC2.dll (my C:\WINDOWS\system32\pthreadVC2.dll).


Third, test pthreads extension

classAsyncOperationextends\thread { Public function__construct ($arg){        $this->arg =$arg; }     Public functionrun () {if($this-Arg) {            printf("Hello%s\n",$this-Arg); }    } }$thread=NewAsyncOperation ("World"); if($thread-start ())$thread-Join(); ?>

Running the above code appears Hello world, indicating that the pthreads extension was successfully installed!

Attach a Thinkphp3.2.2 simple example

<?php namespace Home\controller;classTestextends\thread { Public $url;  Public $result;  Public function__construct ($url) {        $this->url =$url; }         Public functionrun () {if($this-URL) {            $this->result = Model_http_curl_get ($this-URL); }    } } functionModel_http_curl_get ($url) {    $curl=Curl_init (); curl_setopt ($curl, Curlopt_url,$url); curl_setopt ($curl, Curlopt_returntransfer, 1); curl_setopt ($curl, Curlopt_timeout, 5); curl_setopt ($curl, Curlopt_useragent, ' mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2) '); $result= Curl_exec ($curl); Curl_close ($curl); return $result; }  for($i= 0;$i< 10;$i++) {    $urls[] = ' http://www.baidu.com/s?wd= '.Rand(10000, 20000); } /*Multithreading Speed Test*/$t=Microtime(true); foreach($urls  as $key=$url) {    $workers[$key] =NewTest$url); $workers[$key]->start ();} foreach($workers  as $key=$worker) {     while($workers[$key]->isrunning ()) {        Usleep(100); }    if($workers[$key]->Join()) {Dump ($workers[$key]->result); } }$e=Microtime(true);Echo"Multithreaded Time:". ($e-$t)." Seconds <br> "; /*single-thread speed test*/$t=Microtime(true); foreach($urls  as $key=$url) {Dump (Model_http_curl_get ($url)); }$e=Microtime(true);Echo"For loop time:". ($e-$t)." Seconds <br> ";

The test results are as follows:
Multithreading time: 2.83717107772827 seconds
For loop time: 10.9415860176086 seconds
