How to use file system function 'exists' in symfony2? -

i checked symfony2 api docs here,

few file scheme functions available in symfony\component\filesystem\filesystem

i used 'mkdir' , worked fine but, unable utilize 'exists' function

public boolean exists(string|array|traversable $files)

it gives error

fatal error: phone call undefined function survey\blogbundle\controller\exists()

are sure not

bool file_exists ( string $filename )

http://php.net/manual/de/function.file-exists.php

looking @ docs see there exists function. maybe have missed add together utilize statement

use symfony\component\filesystem\filesystem;

however can still utilize file_exists

detailed info on how utilize filesystem http://symfony.com/doc/master/components/filesystem.html

new in version 2.1: filesystem component new symfony 2.1. previously, filesystem class located in httpkernel component.

symfony2
