Keys are always unique, see example:


<?php

$a1 = array("a" => 1, "b" => 2, "c" => 3);

$a2 = array("a" => 10, "d" => 4, "e" => 5);

$a3 = array_merge($a1, $a2);

var_dump($a1);
var_dump($a2);
var_dump($a3);

echo $a3["a"]."\n";

?>

If you haven't named the cells, then it will just merge the arrays 
(append one after the other).
