Add new value in multiple array PHP

Question

I was searching around but still I can't find an answer. I have following array

array:2 [
  0 => array:2 [
    0 => "Name"
    1 => "Age"
  ]
  1 => array:2 [
    0 => "Name"
    1 => "Age"
  ]
]

and I want to add new value 0 in all arrays. This is the result I expect.

array:2 [
  0 => array:2 [
    0 => "Name"
    1 => "Age"
    2 => 0
  ]
  1 => array:2 [
    0 => "Name"
    1 => "Age"
    2 => 0
  ]
]

Thank you.

Try something like.

foreach($array as &$subArray) {

     $subArray[] = 0;
}
var_dump($array);
