In PHP the following is valid:
$n='abc';
echo $n[1];
But it seems that the following 'abc'[1];
is not.
Is there anything wrong with its parser?
Unfortunately currently even $n[1]
syntax is not so useful ◕︵◕ , because it does not support Unicode and returns bytes instead of letters.
echo 'abc'[1];
is only valid in PHP 5.5
see Full RFC but $n[1] or $n{2}
is valid in all versions of PHP
See Live Test

Why not just create yours ?? Example :
$str = "Büyük";
echo $str[1], PHP_EOL;
$s = new StringArray($str);
echo $s[1], PHP_EOL;
// or
echo new StringArray($str, 1, 1), PHP_EOL;
Output
