Hi Expert!

I was unable to find an answer to this situation that I have stumbled uppon this morning. I have declared some php variables as I usually do in javascript (by mistake). I was surprised that the code actually worked. I have tested it under Linux and it works fine. Under WAMP on Windows does not work.

The code:

<?php

error_reporting(E_ALL);

$phones = [];

var_dump($phones);

?>

Result in Linux:

array(0) {

}

Result in Windows:

Parse error: syntax error, unexpected '[' in D:\wamp\www\test.php on line 7

Question: Is this a valid declaration of an array in php?

Thanks in advance!
