Body
ZF version tested on: 2.3.3

An application sometimes receives the following (invalid?) accept header:

Accept: text/html,application/xhtml+xml,application/xml;image/png,image/jpeg,image/*;q=0.9,*/*;q=0.8

This causes an "Undefined offset: 1" notice on line 174 in Zend\Http\Header\AbstractAccept

$value = trim($explode[1]);

it seems already handled at

laminas-http/src/Header/AbstractAccept.php

Line 171 in 176e286

if (count($explode) === 2) {

with count explode variable check. I am closing it. Please re-create issue if the problem persist.
