function module_disable

module_disable($module_list, $disable_dependents = TRUE)

Disables a given set of modules.

Parameters

string[] $module_list: An array of module names.

bool $disable_dependents: If TRUE, dependent modules will automatically be added and disabled in the correct order. This incurs a significant performance cost, so use FALSE if you know $module_list is already complete and in the correct order.
