在php中合并两个或多个数组的值

Question

Someone could be so nice to tell me how to do the following with 2 ore more arrays in PHP:

array 1 (a,b,c,d)
array 2 (1,2,3,4)

I would like to merge the two arrays in an unique array with the merged values:

Result: unique array (a-1,b-2,c-3,d-4).

Is there any function that does so? I could not find anything in the forum either on the web.

Thanks for all your answers but I guess that my arrays are a bit more structured because I need the final result for a dropdown field. Now I have these 2 arrays:

$array1[] = array( 'text' => $hospital['value'], 'value' => $hospital['value'] );
$array2[] = array( 'text' => $company['value'], 'value' => $company['value'] );

I want to have a final array that contains: Hospital1 - Company1, Hospital2 - Company2, Hospital3 - Company3, etc..

Thanks

You would have to create a loop to do this manually. it might look something like the following:

$a = array(a,b,c,d);
$b = array(1,2,3,4);
$c = array(); //result set
if(count($a) == count($b)){ // make sure they are the same length
   for($i = 0; $i < count($a); $i++){
      $c[] = $a[$i]."-".$b[$i];
   }
}
print_r($c);
