Merge two different array based on same key

Question

I have 2 different arrays

First is

(int) 0 => [
        'id' => (int) 1,
        'file_name' => 'test',
        'imported_by' => 'John',
        'valid_to' => (float) 1767225600000
    ],
    (int) 1 => [
        'id' => (int) 2,
        'file_name' => null,
        'imported_by' => 'John',
        'valid_to' => (float) 1767225600000
    ],

Second one is

(int) 0 => object(App\Model\Entity\Product) {
        'id' => (int) 1,
        'product_cat' => (int) 10,
        'product_type' => (int) 1,
        'average....

I have to push first one into second one based on same key

it shoud look like this one

(int) 0 => object(App\Model\Entity\Product) {
        'id' => (int) 1,
        'product_category_id' => (int) 10,
        'product_vessel_id' => (int) 1,
        'average' => test;
        //content from first array
        'file_name' => 'test',
        'imported_by' => 'John',
        'valid_to' => (float) 1767225600000

I have tryied with array_merge_recursive($firstArray,$secondArray); but that mean adding elements on the end of firstArray

Answer 1

$array1 = array(...);
$array2 = array(...);

foreach ( $array1 as $element ) {
  foreach ( $array2 as $object ) {
    if ( $object->id == $element['id'] ) {
         $object->filename = $element['filename'];
         $object->imported_by = $element['imported_by'];
         $object->valid_to = $element['valid_to'];
         break;
    }
  }
}

Answer 2

    <?php
$result = array();
$array_one=array(0 => array('id' =>  1,
        'file_name' => 'test',
        'imported_by' => 'John',
        'valid_to' => 1767225600000),

    1 => array(
        'id' =>  2,
        'file_name' => "",
        'imported_by' => 'John',
        'valid_to' => 1767225600000)



        );


$array_seond=   array(
                    0 => array(
                                'id' =>  1,
                        'product_cat' =>  10,
                        'product_type' =>  1,
                        'average' => 'test'
                    )
                );  


    echo "<pre>";




//print_r($result);

    foreach($array_seond as $key => $value){
                foreach($array_one as $value_second ){

                    if($value['id']==$value_second['id']){
                        $result[$key] =array_merge($array_seond[$key],$value_second);

                    }

                }

    }


    print_r($result);
?>

You can use this function:

function merge_two_arrays($array1,$array2) {
        $data = array();
        $arrayAB = array_merge($array1,$array2);
        foreach ($arrayAB as $value) {
          $id = $value['id'];
          if (!isset($data[$id])) {
            $data[$id] = array();
          }
          $data[$id] = array_merge($data[$id],$value);
        }
        return $data;
      }

    $master_array = merge_two_arrays($array1,$array2);
