note 17063 added to function.getimagesize

ive found that the GetImageSize function can be used quite well for testing for image types, using element [2] of the array. despite the notes of the function, GetImageSize does not return an error code when trying to load a non-image (php4) and instead just returns null. heres a sample of code i put together to test file $img to see if its a valid jpeg file. $size = GetImageSize("$img"); if($size2[2]==2) { echo "$img"." is a valid JPEG image."; } else { echo "$img"." is not a valid JPEG image."; } -- http://www.php.net/manual/en/function.getimagesize.php http://master.php.net/manage/user-notes.php?action=edit+17063 http://master.php.net/manage/user-notes.php?action=delete+17063 http://master.php.net/manage/user-notes.php?action=reject+17063
