This variation of Mike's solution will allow the array keys to be non-numeric and/or non-incrementing.
<?php
foreach($second_array as $key=>$value) {
if(array_key_exists($key, $first_array)) {
array_push($first_array[$key], $value);
} else {
print 'ERROR: Key '.$key.' does not exist in array $first_array.\n';
// or alternatively to add a new sub-array to $first_array
// $first_array[$key] = array($value);
}
}
?>
