Parse error: syntax error, unexpected '['

Hi All,

I got this error when I pull some code from master.
This issue comes due to I have PHP5.3 version which doesn't support [] to create array.

<?php
// php version < PHP 5.4
$array = array(
    '0' => "aaaa",
    '1' => "bbbb",
);

// as of PHP 5.4
$array = [
    '0' => "bar",
    '1' => "foo",
];
?>
