<?php
echo ${!${!1}=ReturnArray()}['a'];
${!${!1}=ReturnArray()}['a']
!1 resolves to false.
${!${false}=ReturnArray()}['a']
false resolves to... I don't know. Let's just say false resolves to "a".
${!$a=ReturnArray()}['a']
$a is now the array. The ! changes the returned array into the
boolean false (like: if (!$handle = fopen('x', 'r')) { echo
'connection failed' }.
${false}['a']
I don't know what false resolves to, but we're using "a".
$a['a']
?>
