PHP: how to add associative keys to a numeric array… without deleting the numeric keys

Question

Say I have an array like this:

$result=array("1", "2", "34");

And I have another array:

 $keys=array("id", "price", "day");

As it is, $result has numeric keys for each of its values. I want to add to those values associative keys, using the values in $keys as such, but without deleting the numeric keys. That is, I want the result to be:

array(6)
{ [0]=> string(1) "1"
  [1]=> string(1) "2"
  [2]=> string(2) "34"
  ["id"]=> string(1) "1"
  ["price"]=> string(1) "2"
  ["day"]=> string(2) "34"
}

I know that I could write a itty-bitty function to do this by hand, but is there any built-in function, among the myriad ones in PHP, to do this automatically? (My PHP knowledge is a bit rusty).

Answer 1

You can do it like this:

$result=array("1", "2", "34");
$keys = array("id", "price", "day");
$array = $result + array_combine($keys, $result);

If you considered using array_merge , I recommend this thread: Array_merge versus +
