基于相同的键合并两个不同的数组

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;
    }
  }
}
