如何让您的php也支持pthreads多线程

　　我们常常会碰到这样一种情况，开发环境在windows下开发，而生产环境确是linux。windows下能正常运行，上传到linux后却无法好好地玩耍了。然后开始了一轮尼玛式的疯狂的查找原因，最后发现是服务器环境问题。这时只能默默地爆一句shit。最近在用php多线程开发一个小功能也碰到类似的问题，在此记录一下。

　　1、查找资料发现php5.3或以上，且线程安全版本，才支持多线程。于是通过phpinfo()查看，发现php版本过低且为非线程安全版本。因而首先需要升级php版本，由于采用了集成式的wdlinux，因而直接采用官网的升级方式。

　　http://www.wdlinux.cn/bbs/thread-8044-1-1.html

　　然而升级后，PHPinfo查看。Thread Safety仍为false，于是继续查找。发现PHP多线程支持，编译时需要添加配置项 --enable-maintainer-zts，这样线程才是安全的（Thread Safety）。创建线程时才不会报错。

　　于是修改下升级脚本，添加--enable-maintainer-zts，然后一步步编译运行。再phpinfo查看，希望的情景终于出现了。

　　2、接下来是添加pthreads扩展

　　PHP扩展下载：https://github.com/krakjoe/pthreads

　　安装pthreads扩展

unzip pthreads-master.zipcd pthreads-master/usr/local/php/bin/phpize./configure ?with-php-config=/usr/local/php/bin/php-configmakemake install

　　3、更改php.ini配置（phpinfo Loaded Configuration File 节点）

　　　　vim /usr/local/php/etc/php.ini
　　添加节点：

　　上一步编译完成之后，会告诉你一个 pthreads.so 文件路径

　　　　extension='/usr/local/php/lib/php/extensions/no-debug-zts-20121212/pthreads.so'

　　以上节点是我机器路径，你们根据自己的情况更改

　　保存、退出
　　4、重启Apache

　　　　/usr/local/apache/bin/httpd -k restart
　　5、测试，直接写个php文件，new Thread，如果能输出类Obj，说明安装成功。
