php 多线程扩展 pthreads 安装 及 使用

1、扩展的编译安装php(Linux），编辑参数 --enable-maintainer-zts 是必选项：
2、下载 php7：
http://tw2.php.net/get/php-7.1.2.tar.gz/from/a/mirrorduoxc

3、解压并编译php
tar -zxf php-7.1.2.tar.gz
cd php-7.1.2
./configure --prefix=/usr/local/php712 --with-config-file-path=/usr/local/php712/etc --with-config-file-scan-dir=/usr/local/php712/etc/php.d --with-mcrypt=/usr/include --enable-mysqlnd --with-mysqli --with-pdo-mysql --enable-fpm --with-gd --with-iconv --with-zlib --enable-xml --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-ftp --enable-gd-native-ttf --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --enable-session --with-curl --with-jpeg-dir --enable-sqlite-utf8 --enable-sysvmsg --enable-sysvshm --enable-wddx --with-xsl --enable-opcache --enable-maintainer-zts

sudo make -j8 && sudo make install

4、php编译完之后开始编译安装 pthreads扩展
5、下载pthreads扩展
https://github.com/krakjoe/pthreads
6、解压并安装
tar -zxf pthreads-3.1.6.tgz
cd pthreads-3.1.6
./configure --with-php-config=/usr/local/php712/bin/php-config
sudo make -j8 && sudo make install

7、配置php.ini
sudo vim /usr/local/php712/etc/php.ini
在 php.ini 最后添加：
[pthreads]
extension=pthreads.so

8、测试pthreads扩展
Thread.php :

<?php
Class Thread {

    public $hooks = array();
    public $args = array();

    public function thread() {

    }

    public function addthread($func) {
        $args = array_slice(func_get_args(), 1);
        $this->hooks[] = $func;
        $this->args[] = $args;
        return true;
    }

    public function runthread() {
        if(isset($_GET['flag'])) {
            $flag = intval($_GET['flag']);
        }

        if($flag || $flag === 0) {
            call_user_func_array($this->hooks[$flag], $this->args[$flag]);
        } else {
            for($i = 0, $size = count($this->hooks); $i < $size; $i++) {
                $fp=fsockopen($_SERVER['HTTP_HOST'],$_SERVER['SERVER_PORT']);

                if($fp) {
                    $out = "GET {$_SERVER['PHP_SELF']}?flag=$i HTTP/1.1rn";
                    $out .= "Host: {$_SERVER['HTTP_HOST']}rn";
                    $out .= "Connection: Closernrn";
                    fputs($fp,$out);
                    fclose($fp);
                }
            }
        }
    }
}

test.php :

include('Thread.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();
}
