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
<?php
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 ");
// 输出结果
HELLO 3 => HELLO 2 => HELLO 4 => HELLO 1 => main
