_configWrite(string|array $key, mixed $value, bool|string $merge = false): void
Writes a config key.
Parameters
-
string|array
$key Key to write to.
-
mixed
$value Value to write.
-
bool|string
$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
