How to merge array and preserve keys?

Question

I have two arrays:

$array1 = array(\'a\' => 1, \'b\' => 2, \'c\' => 3);
$array2 = array(\'d\' => 4, \'e\' => 5, \'f\' => 6, \'a\' => \'n         


        

Answer 1

I think this might help if i understand properly:

foreach ($i = 0, $num = count($array2); $i < $num; $i++)
{
  $array = array_merge($array1, $arrar2[$i]);
}
