mixed —build()
Updates the appropriate cache file
public
build([mixed $title = '' ][, mixed $data = '' ], mixed $unserialize[, mixed $storelocal = true ]) : void
Parameters
- $title : mixed = ''
- $data : mixed = ''
- $unserialize : mixed
- $storelocal : mixed = true
-
-- if we should keep a local copy in memory as if this item had been loaded. This prevents the mass rebuilding of large datastore items from overloading the available memory.
Return values
void —build_options()

public
build_options() : array<string|int, mixed>
After reading the contents of the setting table, the function will rebuild the $vbulletin->options array, then serialize the array and save that serialized array into the 'options' entry of the datastore in the database
