note 36036 added to function.getimagesize

When doing getimagesize() on a gif file, I get the following: 364 240 1 width="364" height="240" 7 3 image/gif I can figure out what most of these mean except for the "7". The documentation available (that I've been able to find) doesn't seem to often go past the 4th parameter (index 3, the 'width and height' string). Also from reading the document above I get the impression that the "3" should be where the "7" is (index 4), as gifs have 3 channels as indicated above. Is the values list out of date? I'm using v4.3.1 on Windows. ---- Manual Page -- http://www.php.net/manual/en/function.getimagesize.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+36036 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+36036&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+36036&report=yes
