When a standard installation method is used, some configuration files of each module (each module is independent) are available in/etc/php5, and then in Cli, Fpm, the directory such as Apache2 contains a conf. d directory, which has a soft connection to the configuration of some modules to be used, so that different configuration files can be loaded in different situations, and only one real module configuration file exists.

Sudo php5enmod mcrypt is to establish a soft connection, and does not declare expansion under php. ini.

PHP expansion has no direct relationship with Apache. The relationship between PHP and apache is a module when the Apache module is running, and the relationship between PHP (Cli) and Apache is a program call when the common Cgi is running.

In general, the # in the corresponding configuration file is canceled, such as/etc/php5/conf. d/ext-mcrypt.ini this file content may have been noted by the well number, use the command # Remove, take effect and Dynamic Load mcrypt. so
