Global Variables¶

Variables in italics may be set in a script prior to the bootstrap process so they are optional.

Exploring Global Variables¶
Many of the global variables described above can be inspected using the ADMIN TOOLS > Configuration module.
警告
This module is always viewed in the BE context. Variables defined only in the FE context will not be visible there.
ノート
This module is purely a browser. It does not let you change values.
It also lets you browse a number of other global arrays. Just be curious and investigate!
