And obviously, I meant to correct line 10, not line 9. >_>

Made a tiny mistake. Obviously, the expected result for line 9 in the script is "a" and
not "123".

Description:
------------
I have only seen documentation for using $var{n} syntax for accessing single characters in strings.
Apparently, it is completely interchangeable with $var[n] for arrays as well. Is this intended?
Seeing as it is only noted that strings may be accessed using curly braces, I would expect the
variable to be typecast to string.
Test script:
---------------
<?php
$foo = array('123');
$bar = 'abc';
echo $foo . "\r\n"; // Outputs "Array", as expected
echo $bar . "\r\n"; // Outputs "abc", as expected
echo $foo[0] . "\r\n"; // Outputs "123", as expected
echo $bar[0] . "\r\n"; // Outputs "123", as expected
echo $foo{0} . "\r\n"; // Outputs "123", undocumented (?), expected implicit
cast to string, thus expected the output to be "A"
echo $bar{0} . "\r\n"; // Outputs "a", as expected
?>
Expected result:
----------------
Array
abc
123
a
A
a
Actual result:
--------------
Array
abc
123
a
123
a
