What are global variables?
Global variables reside in global memory. They need to be pulled into scope before use in a function. The below code brings $context into scope for use inside a function.
global $context;
The global variables are already accessible outside a function so there's no need to bring them into scope. In fact, the call can be done anyway with no harm at all.
List of global variables
SMF contains several globals. Each has its own unique purpose.
General
- $boarddir - a string containing the absolute path to the SMF installation.
