摘要：
最近，我在用PHP多线程开发一个小函数时遇到了类似的问题。让我们在这里记录下来。1.数据发现，只有PHP 5.3或更高版本和线程安全版本支持多线程。通过phpinfo（），我们发现PHP版本太低，而且是非线程安全的。因此，需要首先升级PHP版本。因为使用了集成的wdlinux，所以直接使用官网升级方式。http://www.wdlinux.cn/bbs/thread-8044-1-1.html但是，升级后，PHPinfo会进行检查。“威胁安全”仍然是假的，所以继续搜索。发现PHP支持多线程。编译时，需要添加配置项--enable maintainer zts，以便线程安全。在检查phpinfo之后，最终出现了所需的场景。
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.zip cd pthreads-master /usr/local/php/bin/phpize ./configure –with-php-config=/usr/local/php/bin/php-config make make 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。
