PHP 真正多线程的使用

  PHP 5.3 以上版本,使用pthreads PHP扩展,可以使PHP真正地支持多线程。多线程在处理重复性的循环任务,能够大大缩短程序执行时间。

  我之前的文章中说过,大多数网站的性能瓶颈不在PHP服务器上,因为它可以简单地通过横向增加服务器或CPU核数来轻松应对(对于各种云主机,增加VPS或CPU核数就更方便了,直接以备份镜像增加VPS,连操作系统、环境都不用安装配置),而是在于MySQL数据库。如果用 MySQL 数据库,一条联合查询的SQL,也许就可以处理完业务逻辑,但是,遇到大量并发请求,就歇菜了。如果用 NoSQL 数据库,也许需要十次查询,才能处理完同样地业务逻辑,但每次查询都比 MySQL 要快,十次循环NoSQL查询也许比一次MySQL联合查询更快,应对几万次/秒的查询完全没问题。如果加上PHP多线程,通过十个线程同时查询NoSQL,返回结果汇总输出,速度就要更快了。我们实际的APP产品中,调用一个通过用户喜好实时推荐商品的PHP接口,PHP需要对BigSea NoSQL数据库发起500~1000次查询,来实时算出用户的个性喜好商品数据,PHP多线程的作用非常明显。


  1、扩展的编译安装(Linux),编辑参数 --enable-maintainer-zts 是必选项:
cd /Data/tgz/php-5.5.1
./configure --prefix=/Data/apps/php --with-config-file-path=/Data/apps/php/etc --with-mysql=/Data/apps/mysql --with-mysqli=/Data/apps/mysql/bin/mysql_config --with-iconv-dir --with-freetype-dir=/Data/apps/libs --with-jpeg-dir=/Data/apps/libs --with-png-dir=/Data/apps/libs --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt=/Data/apps/libs --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-opcache --with-pdo-mysql --enable-maintainer-zts
make clean
make install        

cd pthreads-master
./configure --with-php-config=/Data/apps/php/bin/php-config
make install

vi /Data/apps/php/etc/php.ini

extension = ""
