Parse error on explode('-','foo-bar')[0] (for instance)

In PHP there are functions that return an array, for example:

$a = parse_url("https://stackoverflow.com/q/9461027/87015");
echo $a["host"]; // stackoverflow.com

My question is how to combine the above two statements into a single statement. This (is something that works in JavaScript but) does not work:

echo parse_url("https://stackoverflow.com/q/9461027/87015")["host"];

Note: function array dereferencing is available since PHP 5.4; the above code works as-is.

You can do a little trick instead, write a simple function

function readArr($array, $index) {
    return $array[$index];
}

Then use it like this

echo readArr(parse_url("http://stackoverflow.com/questions/9458303/how-can-i-change-the-color-white-from-a-uiimage-to-transparent"),"host");
