Settings Class

Settings is a read-only config loader used by Instructor packages. Most relevant methods:
  • setPath(string $dir) - override config search path
  • flush() - clear cached config and reset custom paths
  • has(string $group, ?string $key = null) - check group/key existence
  • get(string $group, string $key, mixed $default = null) - read value
  • getGroup(string $group) - read full config group as array
  • hasGroup(string $group) - check if group file exists
Notes:
  • There is no mutable set(group, key, value) API.
  • Path resolution supports both INSTRUCTOR_CONFIG_PATHS and INSTRUCTOR_CONFIG_PATH.
