What should I do if the thread cannot be found in php ?

Specific problem description:

我在网络服务器上使用php5.5.现在，我想使用pthreads.这是我的php配置: http://dd19010.kasserver.com/infophp.php55

实现此代码后.....

 <?php

class AsyncOperation extends Thread
{
    public function __construct($threadId)
    {
        $this->threadId = $threadId;
    }

    public function run()
    {
        printf("T %s: Sleeping 3sec\n", $this->threadId);
        sleep(3);
        printf("T %s: Hello World\n", $this->threadId);
    }
}

$start = microtime(true);
for ($i = 1; $i <= 5; $i++) {
    $t[$i] = new AsyncOperation($i);
    $t[$i]->start();
}
echo microtime(true) - $start . "\n";
echo "end\n";

?>
...问题是这个错误:致命错误:在中找不到类&#39;Thread&#39;. 我是否必须包含一些 include_once 或类似的东西才能使其正常工作? 我该怎么办?

Solution:

First of all, please consider the VC version of PHP and VC version of extension. In my system I attached VC14 version with extension pthreads.dll from http://windows.php.net/downloads/pecl/releases/pthreads/ but my PHP VC version is VC11. Look for a lower version that matches the VC version of PHP.

Second, maybe you missed step 3 on the PHP page. It states that you need to copy pthreadVC2.dll to a different folder. Here are the complete instructions.

Use phpinfo() to find out what the "PHP Extension Build" version is. You can use this - http://localhost/?phpinfo=1

Download with pthreads that match your PHP version (32-bit or 64-bit) and PHP extensions version (currently using VC11). Use this link to download - http://windows.php.net/downloads/pecl/version/pthreads/

Unzip - Move php_pthreads.dll to the "bin\php\ext\" directory. Move pthreadVC2.dll to the "bin\php\" directory. Move pthreadVC2.dll to "bin\apache\bin "Directory. Move pthreadVC2.dll to the "C:\windows\system32" directory.

Open php\php.ini and add extension = php_pthreads.dll
