Actually, the default value is count($input)[1]. It's definitely not NULL, though, see <https://3v4l.org/6AAFC>.

When I look in my IDE however it has the following, which I believe is correct: function array_splice (array &$input, $offset, $length = null, $replacement = null) {} ------------------------------------------------------------------------ [2016-09-30 08:16:19] cmb@php.net No, 0 is the default value, i.e. without passing a $length, the function behaves as if 0 was passed. ------------------------------------------------------------------------ [2016-09-30 01:15:31] nick at nickduffell dot com dot au Description: ------------ --- From manual page: http://www.php.net/function.array-splice --- Default value for $length is shown as 0, but it should be null. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73205&edit=1
