<?php
function ReturnArray() {
   return array('a' => 'f', 'b' => 'g', 'c' => 'h', 'd' => 'i', 'e' =>
'j');
}

echo ${!${!1}=ReturnArray()}['a']; // 'f'

ya; i never did sit down and try to figure out how that works; care to
explain ?

<?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']
?>

Just awesome! Thanks for the explanation Casey, and thanks for the archived link Nathan. I knew I'd learn something by asking.
