坑爹php多线程安装和使用

参考：http://www.manongjc.com/article/1503.html（安装）
https://segmentfault.com/q/1010000004327568?_ea=575102（问题详解）

我这边使用的是安装php7.3+pthread

• 装php前要安装下apt-get install autoconf
• 安装php时候configure要加上–enable-maintainer-zts，然后就是常规流程php -v看版本号
• 下载pthread，扩展安装传送门,安装流程如下

cd pthreads
/usr/local/php7.3/etc/phpize
./configure --with-php-config=/usr/local/php7.3/bin/php-config
make
make install

• 然后去/usr/local/php7.3/etc下执行cp php.ini php-cli.ini再将extension = "pthreads.so"添加到后面，同时执行php -m就看到pthreads了,这边都不需要启动php-fpm后台任务，因为使用cli模式会优先读取php-cli.ini配置里的内容。

最后贴测试代码

<?php

class RequestUrl extends \Thread
{
    public $url;
    public $response;
    public function __construct($url) {
        $this->url = $url;
    }
    public function run() {
        $this->response = $this->modelHttpCurlGet($this->url);
    }

    public function modelHttpCurlGet($url,$userAgent="")
    {
        $userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_TIMEOUT, 5);
        curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
        $result = curl_exec($curl);
        curl_close($curl);
        return $result;
    }
}

<?php
require_once('RequestUrl.php');

function model_thread_result_get($urlsArray)
{
    foreach ($urlsArray as $key => $value)
    {
        $threadArray[$key] = new RequestUrl($value["url"]);
        $threadArray[$key]->start();
    }

    foreach ($threadArray as $thread_array_key => $thread_array_value)
    {
        while($threadArray[$thread_array_key]->isRunning())
        {
            usleep(10);
        }
        if($threadArray[$thread_array_key]->join())
        {
            $variableData[$thread_array_key] = $threadArray[$thread_array_key]->data;
        }
    }
    return $variableData;
}

for ($i=0; $i < 100; $i++)
{
    $urls[] = [
        "name" => "baidu",
        "url" => "http://www.baidu.com/s?wd=".mt_rand(10000,20000)
    ];
}

// 多线程测试
$startTimeThread = microtime(true);
$result = model_thread_result_get($urls);
$endTimeThread = microtime(true);
echo "多线程：".($endTimeThread-$startTimeThread)."\n";

// for循环测试
$t = microtime(true);
foreach ($urls as $key => $value)
{
    $requestUrl = new RequestUrl('');
    $result_new[$key] = $requestUrl->modelHttpCurlGet($value["url"]);
}
$e = microtime(true);
echo "For循环：".($e-$t)."\n";


?>

本地执行php Test.php
显示

或者如果想看下线程数

可以将链接数改成100000个，然后跑，再看top

发现php跑的进程id为60895，再执行pstree -p 6089 | wc -l查看该进程下的线程数量

—分割线–

多进程，线程测试保留代码
