thinkphp 3.1 configuration

ThinkPHP provides a flexible global configuration function, which is defined using the most efficient PHP return array method. It supports conventional configuration, project configuration, group configuration, debugging configuration and dynamic configuration, and automatically generates configuration cache files without repeated parsing. of overhead. For some simple applications, you do not need to configure any configuration files, and for complex requirements, you can also add dynamic configuration files.

ThinkPHP has created its own unique hierarchical configuration model in project configuration, and its configuration level is reflected in:

Conventional configuration->Project configuration->Debug configuration->Group configuration->Extended configuration->Dynamic configuration

The above is the loading order of configuration files. Because the later configuration will overwrite the previous configuration with the same name (if it does not take effect), the priority is from right to left. The system configuration parameters are globally accessed through static variables, and the access method is simple and efficient.

Debug configuration (no cache)

APP_STATUS=>'dubug' then the configuration file is debug.php

Group configuration

APP_GROUP_LEST=>'Admin,Home',//Group

DEFAULT_GROUP=>'HOME',//Default group

Note: Group names are case sensitive

Dynamic Grouping

Use system function: C (name, value) to dynamically set and obtain the value of the configuration file

Extended configuration (not affected by compilation)

LOAD_EXT_CONFIG=>'user,map'

Load user.php map.php and other files

Configuration file name occupied by the system
