pthread在PHP中不起作用 [英] pthread not working in php

问题描述

我已经从 PHP Pthreads dll文件. php.net/downloads/pecl/releases/pthreads/"rel =" nofollow> http://windows.php.net/downloads/pecl/releases/pthreads/并在php.ini中启用它，如下所示:

I have downloaded the PHP Pthreads dll file from http://windows.php.net/downloads/pecl/releases/pthreads/ and enabled it in php.ini as below:

extension=pthreadVC2.dll
extension=php_pthreads.dll

我使用了以下示例代码:

I have used below sample code:

<?php
class AsyncOperation extends Thread 
{
    public function __construct($arg){
        $this->arg = $arg;
    }

    public function run(){
        if($this->arg){
            printf("Hello %s\n", $this->arg);
        }
    }
}

$thread = new AsyncOperation("World");
if($thread->start())
    $thread->join();

当我执行代码时，出现以下错误:

when i executed the code i get the following error:

致命错误:在C:\ htdocs \ threads \ AsyncOperation.php中找不到类'Thread' 第2行调用堆栈:0.0008 333464 1. {main}() C:\ htdocs \ threads \ AsyncOperation.php:0

Fatal error: Class 'Thread' not found in C:\htdocs\threads\AsyncOperation.php on line 2 Call Stack: 0.0008 333464 1. {main}() C:\htdocs\threads\AsyncOperation.php:0

推荐答案

这里有两个问题:

1)首先必须正确查找dll文件的位置. dll文件应放置如下:

1) First have to look for dll files location correctly. dll files should be placed as below:

C:\PHP5\pthreadVC2.dll
C:\PHP5\ext\php_pthreads.dll

，并且在php.ini文件中，仅应将php_pthreads.dll启用为

and in php.ini file only php_pthreads.dll should be enabled as

extension=php_pthreads.dll

2)必须查找PHP和dll文件的版本.

2) Have to look for Versions of PHP and dll file.

我的PHP是VC6构建版本，使用的dll文件是VC9.这就是为什么未安装模块的原因.我通过使用" php -m "来了解这种区别.

My PHP is VC6 build and dll file used is VC9. Thats why module didn't get installed. I came to know this difference by using "php -m".

由于没有VC6版本的dll文件，因此我使用了VC9版本的PHP和pthreads，并且程序运行正常.

Since there is no VC6 build of dll file, I have used VC9 build of PHP and used pthreads and the program is working perfectly.

注意:以上两种解决方案解决了我的问题.但是，如果仍然出现错误，请检查是否启用了调试器xdebug或zend.禁用它们，然后重试.

Note:The above two solutions solved my problems. But if you are still getting errors check if you have debuggers enabled xdebug or zend. Disable them and try again.
