Php – Count the column of array

In this array output, how can I count the type column? Or better, how can I exclude the addition_data when counting it? Answer should be 3 since there are only 3 type column

Array (
    [124] => 
        Array (
            [type] => 0
            [value] => 4 Pack
            [label] => 4 Pack
            )
    [125] => 
        Array (
            [type] => 0
            [value] => 6 Pack
            [label] => 6 Pack
        )
    [126] => 
        Array (
            [type] => 0
            [value] => 12 Pack
            [label] => 12 Pack
        )
    [additional_data] => {"swatch_input_type":"text","update_product_preview_image":"1","use_product_image_for_swatch":0} )

Tried
count(array_column($swatchLists, 'type'));

But it’s outputting 0

    Please try this code

    $countResult = array();

foreach( $swatchLists as $item ){
    if( isset($item['type']) == false ){
        continue; // excluding the array which does NOT contains the 'type'
    }
    $type = $item['type'];
    if( isset($countResult[$type]) ){
        $countResult[$type]++;
    }else{
        $countResult[$type] = 1;
    }
}
var_dump($countResult);

    every types of count will be store into $countResult, the array-key is the type value, the array-value is the count.

    One way would be to filter out the items with array_filter:

    $input = [
  124               => [ 'type' => 0, 'value' => '4 Pack', 'label' => '4 Pack' ],
  125               => [ 'type' => 0, 'value' => '6 Pack', 'label' => '6 Pack' ],
  126               => [ 'type' => 0, 'value' => '12 Pack', 'label' => '12 Pack' ],
  'additional_data' => '{"swatch_input_type":"text","update_product_preview_image":"1","use_product_image_for_swatch":0}'
];

$items = array_filter(
  $input,
  fn($value, $key) => is_int($key) && array_key_exists('type', $value),
  ARRAY_FILTER_USE_BOTH
);

echo count($items);   // Output: 3
