#35061 [Opn->Bgs]: imagegif,png,ipg.second parameter can not be set ''(null)

ID: 35061 Updated by: vrana@php.net Reported By: surfchen at gmail dot com -Status: Open +Status: Bogus Bug Type: Documentation problem Operating System: Redhat AS PHP Version: 4.4.0 New Comment: Third and fourth parameter of this function is silently ignored. Empty string for the second parametr can be used to skip it but if a function has only two parameters, there's nothing to skip and the second parameter is used. If you just want to output the image, simply call imagegif($img).
