PHP Expansion Module Installation

When compiling httpd, there are dynamic and static modules involved, PHP also has static and dynamic points, the previous PHP installation is all static, and there is no dynamic module, so-called dynamic, is an independent existence of the. so file, in httpd PHP is loaded in the form of dynamic modules. Once PHP is compiled, if you want to add another feature, either recompile PHP or simply compile an extension (generate a. so file) and then configure it in php.ini to be loaded and used.

1. View PHP-loaded modules

3. Modify the PHP configuration file to make the extension effective

[[email protected] phpredis-develop]# vim /usr/local/php/etc/php.ini    //添加以下内容extension = redis.so[[email protected] phpredis-develop]# /usr/local/php/bin/php -m | grep redis    //查看是否加载了redisredis
