Push data to elements in array in php

$array = array(array("a"=>1),array("a"=>2));

I need to push data to sub array element in $array,

End result must be as follow,

 Array ( [0] => Array ( [a] => 1 [b] => 2 ) [1] => Array ( [a] => 2 [b] => 2 ) )

I used following ways .

  1. foreach($array as &$a){ $a['b']=2;}

  2. $result = array_map("pushdata",$array);

    function pushdata($a){
$a['b']=2;
}

what is the most suitable and performance high way when $array consists of more than 1000 records ?

Here is an example using array_walk() to add a new key b to each sub-array:

$array = array(array('a' => 1), array('a' => 2));
array_walk($array, function(&$item, $key) {
  $item['b'] = 2;
});
print_r($array);
/* outputs:
Array
(
  [0] => Array
  (
      [a] => 1
      [b] => 2
  )
  [1] => Array
  (
      [a] => 2
      [b] => 2
  )
)

Use array_walk , to iterate over the array and array_push to push the element to each iteration.

Here is an example for 5 items.

<?php

  for($i = 1 ; $i<5 ; $i++){
     $array[] = array("a"=>$i,"b"=>2);
  }

  print_r($array);

?>
