Description:
------------
Strings offsets in PHP5 are broken strangely. Seems like repeated offsets are not allowed at all, even at the times where they make good sense.

I see nothing fatal in $a[0][0] or even $a{0}{0} or even $a[0]{0}[0] if $a is a non-empty string. And PHP5 just crashes at any one of them.

Why $a{0} can't be a string without extra intermediate assignment?

Please, look at the code before marking bogus.

Reproduce code:
---------------
<?
$a = '0';
$b = $a[0];
echo $b[0];

$a = '0';
// leave any one line of the next few
echo $a[0][0];
echo $a[0]{0};
echo $a{0}{0};
echo $a[0]{0}[0];
?>

Expected result:
----------------
00

Actual result:
--------------
0
