Module config 

Structs

DiagnosticsConfig

Per-category diagnostic toggle flags. The master enabled switch defaults to true. Individual category flags also default to true, so all diagnostics are on out of the box; set initializationOptions.diagnostics.enabled = false to silence everything, or turn off specific categories individually.

FeaturesConfig

Per-feature capability toggles. All default to true (enabled). Set initializationOptions.features.<name> = false to suppress a capability.

LspConfig

Configuration received from the client via initializationOptions.

Constants

MAX_INDEXED_FILES

Maximum number of PHP files indexed during a workspace scan. Prevents excessive memory use on projects with very large vendor trees.
