Need help splitting an array

Question

Hi i am trying to split an array into 2 or more arrays. Here is what i am trying to do:

My array:

array(size=5)
  0=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'
  1=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'
  2=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'
  3=>
    array(size=3)
      'oid' => int 2
      payment_status => 'Paid'
      payment_type => 'Online'
  4=>
    array(size=3)
      'oid' => int 2
      payment_status => 'Paid'
      payment_type => 'Online'

I am trying to split this array like this:

array(size=3)
  0=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'
  1=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'
  2=>
    array(size=3)
      'oid' => int 1
      payment_status => 'Paid'
      payment_type => 'Online'

and

array(size=2)
  0=>
    array(size=3)
      'oid' => int 2
      payment_status => 'Paid'
      payment_type => 'Online'
  1=>
    array(size=3)
      'oid' => int 2
      payment_status => 'Paid'
      payment_type => 'Online'

So as you can see the array gets split into multiple arrays based on 'oid' value. Can anyone tell me how to achieve this output? Thanks

Answer 1

simple one, copy the items based on oid into a new array:

$input = $yourArray;

$output = array();

foreach($input as $item)
{
    $output[$item['oid']][] = $item;
}

var_dump($output);

output holds an array with oid as key.

you can access your separated array like this:

$output[1]; //for oid 1
$output[2]; //for oid 2

and so on
