Unlink file in CodeIgniter

If you try to use unlink in CI as $filestring  =  base_url ( ) . 'uploads/' . $ filename ; unlink  (  $filestring ) ; you will face such error message: A PHP Error was encountered Severity: Warning Message: unlink() [function.unlink]: http does not allow unlinking Filename: controllers/face.php Line Number: 109 because CI does not understand the  path we specified, therefore to remove a file we have to either use: $filestring  =  APPPATH .
