I have an array which is expressed in this way:

$id = $values['ids'];

Result:

array(6) { [0]=> string(1) "4" [1]=> string(1) "6" [2]=> string(1) "7" [3]=> string(1) "8" [4]=> string(1) "9" [5]=> string(2) "10" }

Originally, I was imploding this array so that I could pass it off as a value to use in $_POST:

$id = implode(",", $values['ids']);

Result:

string(12) "4,6,7,8,9,10"

In my $_POST page, I need to revert back to the original array, but when I use explode, I now get this result:

$id2 = explode(" ", $id);
//array(1) { [0]=> string(12) "4,6,7,8,9,10" }

I think the issue is how I am imploding this in the first place - it's making the individual values as one string, but not sure what to do in order to get the result I need. I need to pass the array on as a value, and then put it back into the original format that it was in as the array. Does anyone know what I should do?

  • Please add your current code/attempt into your question. Commented May 16, 2015 at 22:47
  • What delimiter did you use when you tried explode()? Commented May 16, 2015 at 22:52
  • Actually - I think I answered my own question. If I find that I am still having issues I will re-ask this with the code so as to not cause confusion. Commented May 16, 2015 at 22:54

    @Wes Just add your code to your question and add more details if you think you have to specify your problem more. Commented May 16, 2015 at 22:55
  • I've updated it to reflect the issue. I was thinking these needed to be ints but they don't. Hope it makes more sense now. Commented May 16, 2015 at 23:12

Use explode and array_map with intval as callback:

$nums = "4,6,7,8,9,10";
$intsArray = array_map('intval', explode(',', $nums));
var_dump($intsArray);

Output:

array(6) {
  [0]=>
  int(4)
  [1]=>
  int(6)
  [2]=>
  int(7)
  [3]=>
  int(8)
  [4]=>
  int(9)
  [5]=>
  int(10)
}

I think I just answered my own question. It was in the way I was using explode. Should be:

$id2 = explode(',', $id);

And not:

$id2 = explode(" ", $id);

I'll give credit to Pedro who caused me to realize this when he pasted his example.

Thanks for the mention but array $id2 still contains strings and not ints as the OP want, use var_dump($id2); to confirm that.
@PedroLobito OP doesn't need integers: stackoverflow.com/questions/30281507/… And ^^ this is OP...
Hi @Rizier123, almost at 30k ;) The question was updated, the original contained a request for an array with ints. I didn't realize this was the OP.... I probably miss a coffee...
@PedroLobito Well I had the same answer prepared as you have, but I didn't posted it, because the: string(12) "4,6,7,8,9,10" was suspicious for me. (FYI: ^ See the blue box around the user name? That's the indication, that the post is from OP)

Easily you can use json_encode and json_decode functions. For example:

$a = array(1,2,3,4,5);

$b = json_encode($a);
var_dump($b);

$c = json_decode($b);
var_dump($c);

that result of run is:

meysampg@freedom:~/www/testFunc$ php json_deEncode.php 
string(11) "[1,2,3,4,5]"
array(5) {
  [0] =>
  int(1)
  [1] =>
  int(2)
  [2] =>
  int(3)
  [3] =>
  int(4)
  [4] =>
  int(5)
}
