phph Array dereferencing

<?phpfunction getArray() {
    return array(1, 2, 3);
}// on PHP 5.4$secondElement = getArray()[1];// previously$tmp = getArray();$secondElement = $tmp[1];// orlist(, $secondElement) = getArray();?>





// previously
$tmp = getArray();
$firstElement = $tmp[0];
$secondElement = $tmp[1];

// or
var_dump (list($firstElement, $secondElement) = getArray());

echo '**'.$firstElement;
echo '**'.$secondElement;


 

Note:

Attempting to access an array key which has not been defined is the same as accessing any other undefined variable: an E_NOTICE-level error message will be issued, and the result will be NULL.
