it is a way to create an array. It is not realy a function.

An array is sort of a list.

You can initialize with any number of elements:

$emptyArray = array();
$oneItemArray = array('item');
echo $oneItemArray[0]; // => "item"
$twoItemArray = array('item 1', 'item 2');
echo $oneItemArray[0]; // => "item 1"
echo $oneItemArray[1]; // => "item 2"

Oh I see, but you have to admit it looks just like a function (-:

It's a language construct, just like list($a, $b) = array('valueForA', 'valueForB'); (syntax to set $a to 'valueForA', and $b to 'valueForB');
