PHP - manipulating an array

I want to manipulate an array and i'm a bit stuck on how to proceed and hoping i can be pointed to the right direction

This is the array i currently have:

array(10) {
["gdlr-room-id"]=> string(4) "3595"
["gdlr-check-in"]=> string(10) "2016-10-31"
["gdlr-night"]=> string(1) "1"
["gdlr-check-out"]=> string(10) "2016-11-01"
["gdlr-room-number"]=> string(1) "1"
["gdlr-adult-number"]=> string(1) "1"
["gdlr-children-number"]=> string(1) "1"
["gdlr-resident"]=> string(8) "resident"
["service"]=> string(19) "5061,5060"
["service-amount"]=> string(7) "1,1" }


And this is what i want to achieve:

array(10) {
["gdlr-room-id"]=> array(1) { [0]=> string(4) "3595" }
["gdlr-check-in"]=> string(10) "2016-10-31"
["gdlr-night"]=> string(1) "1"
["gdlr-check-out"]=> string(10) "2016-11-01"
["gdlr-room-number"]=> string(1) "1"
["gdlr-adult-number"]=> array(1) { [0]=> string(1) "1" }
["gdlr-children-number"]=> array(1) { [0]=> string(1) "1" }
["gdlr-resident"]=> string(8) "resident"
["service"]=> array(2) { [0]=> string(4) "5061" [1]=> string(4) "5060" }
["service-amount"]=> array(2) { [0]=> string(1) "1" [1]=> string(1) "1" }
}


If i can explain a bit more: if we take the key gdlr-room-id as an example: my current array represents a key, value pair as shown
["gdlr-room-id"]=> string(4) "3595"
while my desired result is for the value to be inside another array as shown:
["gdlr-room-id"]=> array(1) { [0]=> string(4) "3595" }
. This is not for all the key=>value pairs but only a select few as some would remain as they are e.g.
["gdlr-check-in"]=> string(10) "2016-10-31"
is ok as it is

In summary, how do i take some values inside an array(as my current one is) and make some values be inside another array as i have explained above? and while we're at it, any suggestion how i can turn this
["service"]=> string(19) "5061,5060"
into this:
["service"]=> array(2) { [0]=> string(4) "5061" [1]=> string(4) "5060" }
? thanks

Answer

If you have a list of keys for which the value should be expanded into arrays, e.g.

$expand_keys = array('gdlr-room-id', 'service');

and multiple values are separated by commas, you could do something like

foreach ($array as $key => $value) {
  if (in_array($key, $expand_keys)) {
    $array[$key] = explode(',', $value);
  }
}

This will check each key-value pair of your original array and explode its value into an array if the key is in the $expand_keys array.
