We promote the respective notice to a caution, move it up, and explain that the returned array may contain nonsense. ------------------------------------------------------------------------ [2017-03-17 11:58:59] cmb@php.net From the manual[1]: | This function expects filename to be a valid image file. If a | non-image file is supplied, it may be incorrectly detected as an | image and the function will return successfully. This notice should better be moved to a more prominent place, and be improved. So I'm changing to doc-bug.

Whene I use getimagesize() PHP function then it returns array:6 [▼ 0 => 16188 1 => 26736 2 => 1 3 => "width="16188" height="26736"" "channels" => 3 "mime" => "image/gif" ] although image is not valid but still it has valid width and height. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74239&edit=1
