I can't seem to find any discussion on this BC issue, so forgive me if
this has already been discussed.
Given the following;
$a = 'a string';
/* E_ERROR Cannot use string offset as an array */
echo is_array($a['bar']['baz']);
/* non error resolution */
echo isset($a['bar']['baz']) && is_array($a['bar']['baz']);
I'm not sure, but the patch below does seem to make the E_ERROR
get demoted to a E_WARNING, thus fixing it so execution simply doesn't
stop when a string is referenced improperly. Or is it a *must* that php
needs to stop in this case?
