PHP7.2 安装 PThread

通过本篇,能学会如何安装PHP7.2版本的PThread.(项目中没使用到...)


前言:

      之前想通过PHP多线程分批去处理请求,等最后安装好,运行成功后才发现官方的一句话,最后不得不放弃使用了。

SAPI Support

pthreads v3 is restricted to operating in CLI only: I have spent many years trying to explain that threads in a web server just don't make sense, after 1,111 commits to pthreads I have realised that, my advice is going unheeded.

So I'm promoting the advice to hard and fast fact: you can't use pthreads safely and sensibly anywhere but CLI.

Thanks for listening ;)


安装:

    1,我是使用oneinstack 集成工具,安装Thread前需要在oneinstack/options.conf 增加php编译扩展(开启安全模式)

    php_modules_options='--enable-maintainer-zts '

      2,检查是否已开启安全线程

    php -i | grep Thread  => 看到enable 表示是安全版

      3,下载最新的Pthreads扩展

    git clone https://github.com/krakjoe/pthreads.git

      4,在下载好的pthreads目录下执行phpsize命令

    phpize

      5,执行安装命令

    ./configure --with-php-config=/usr/local/php/bin/php-config    
    make && make install

      6,写入配置文件

        echo "extension=pthreads.so" >> /usr/local/php/etc/php.ini

      7,测试代码

                class My extends Thread {
                    public function run() {
                       sleep(10);
                        echo("HELLO 1 \r\n");
                    }
                }
                
                class My2 extends Thread {
                    public function run() {
                        /* ... */
                       sleep(3);
                       echo("HELLO 2 \r\n");
                    }
                }
                
                
                
                class My3 extends Thread {
                    public function run() {
                        /* ... */
                       sleep(1);
                       echo("HELLO 3 \r\n");
                    }
                }
                
                
                class My4 extends Thread {
                    public function run() {
                        /* ... */
                      sleep(5);
                       echo("HELLO 4 \r\n");
                    }
                }
                
                
                $my_1 = new My();
                $my_2 = new My2();
                $my_3 = new My3();
                $my_4 = new My4();
                
                $my_1->start();
                $my_2->start();
                $my_3->start();
                $my_4->start();
                
                $my_1->join();
                $my_2->join();
                $my_3->join();
                $my_4->join();
                echo("main ");
                
              
                
                ECHO
                HELLO 3 => HELLO 2 => HELLO 4 => HELLO 1 => main
