How can I merge PHP arrays?

Question

I have two arrays of animals (for example).

$array = array(
    array(
        \'id\' => 1,
        \'name\' => \'Cat\',
    ),
    array(
        \'id         


        

Answer 1

First off, why don't you use the ID as the index (or key, in the mapping-style array that php arrays are imo)?

$array = array(
    1 => array(
        'name' => 'Cat',
    ),
    2 => array(
        'name' => 'Mouse',
    )
);

after that you'll have to foreach through one array, performing array_merge on the items of the other:

foreach($array2 as $key=>$value) {
  if(!is_array($array[$key])) $array[$key] = $value;
  else $array[$key] = array_merge($array[key], $value); 
}

Something like that at least. Perhaps there's a better solution?
