Since: 1.1 Added method.
Since: 2.0 Method now fails if $path is not a string.
public static getExtension ( string $path, boolean $forceLowerCase = false ) : string

$forceLowerCase boolean Forces the extension to be lower-case (requires mbstring extension for correct multi-byte character handling in extension).
