<?php
$var['a'] = 'test';

echo isset($var['a']['b']) ? 'true' : 'false';
echo '<br>';
echo isset($var['b']) ? 'true' : 'false';
?>

Why does that result in this output?:

true
false

It seems to me that it should instead output this:

false
false

Using array_key_exists instead works, but I'm not sure why isset
doesn't? Is this maybe a PHP bug?
