Combine two arrays into one by keys

Question

Array( [0] => Array ( [orders] => 5 [manager_customer_id] => 85 ) [1] => Array ( [orders] => 1 [manager_customer_id] => 124 ) [2] => Array ( [orders] => 6 [manager_customer_id] => 86 ) ) Array( [0] => Array ( [name_manager_customer] => Nick Name [manager_customer_id] => 85 [manager_id] => 699 [city_manager_customer] => [shop_manager_customer] => [phone_manager_customer] => [vk_id_manager_customer] => just_nick_name [card_number] => [card_name] => ) [1] => Array ( [name_manager_customer] => Queen Time [manager_customer_id] => 124 [manager_id] => 699 [city_manager_customer] => [shop_manager_customer] => [phone_manager_customer] => [vk_id_manager_customer] => [card_number] => [card_name] => ) [2] => Array ( [name_manager_customer] => БигБен [manager_customer_id] => 86 [manager_id] => 699 [city_manager_customer] => [shop_manager_customer] => [phone_manager_customer] => [vk_id_manager_customer] => [card_number] => [card_name] => ) )

They have the same manager_customer_id nor how can I figure out how to combine what would happen

 Array( [0] => Array ( [name_manager_customer] => Nick Name [manager_customer_id] => 85 [manager_id] => 699 [city_manager_customer] => [shop_manager_customer] => [phone_manager_customer] => [vk_id_manager_customer] => just_nick_name [card_number] => [card_name] => [orders] => 5 ) )

Take your raw data

 $orders = [ ['orders' => 5, 'manager_customer_id' => 85], ['orders' => 1, 'manager_customer_id' => 124], ['orders' => 6, 'manager_customer_id' => 86] ]; $data = [ [ 'name_manager_customer' => "Nick Name", 'manager_customer_id' => 85, 'manager_id' => 699, ], [ 'name_manager_customer' => "Queen Time", 'manager_customer_id' => 124, 'manager_id' => 699, ], [ 'name_manager_customer' => "БигБен", 'manager_customer_id' => 86, 'manager_id' => 699, ] ];

and convert the first array to a convenient form, where identifiers will be keys

 $odata = array_column($orders, 'orders', 'manager_customer_id');

go through the second array and set the values

 foreach($data as &$d){ $d['orders'] = $odata[$d['manager_customer_id']]; }

If it is not necessary to touch the second array, then add the result to the third

 $result = []; foreach($data as $d){ $d['orders'] = $odata[$d['manager_customer_id']]; $result[] = $d; }

Another option:

 <?php $a_1 = array( array( 'orders' => 5, 'manager_customer_id' => 85 ), array( 'orders' => 1, 'manager_customer_id' => 124 ), array( 'orders' => 6, 'manager_customer_id' => 86 ) ); $a_2 = array( array( 'name_manager_customer' => 'Nick Name', 'manager_customer_id' => 85, 'manager_id' => 699, 'city_manager_customer' => '', 'shop_manager_customer' => '', 'phone_manager_customer' => '', 'vk_id_manager_customer' => 'just_nick_name', 'card_number' => '', 'card_name' => '' ), array( 'name_manager_customer' => 'Queen Time', 'manager_customer_id' => 124, 'manager_id' => 699, 'city_manager_customer' => '', 'shop_manager_customer' => '', 'phone_manager_customer' => '', 'vk_id_manager_customer' => '', 'card_number' => '', 'card_name' => '' ), array( 'name_manager_customer' => '', 'manager_customer_id' => 86, 'manager_id' => 699, 'city_manager_customer' => '', 'shop_manager_customer' => '', 'phone_manager_customer' => '', 'vk_id_manager_customer' => '', 'card_number' => '', 'card_name' => '' ) ); $result = []; for ($i = 0, $all = count($a_1); $i < $all; $i++) { $result[] = array_merge($a_2[$i], $a_1[$i]); } echo '<pre>'; print_r($result); echo '</pre>';

Duck there is a question then that it is not necessary to add in pairs, but according to coincident identifiers, and the order may be different.
@ Sender1050 seems to be correct: sandbox.onlinephpfunctions.com/code/… Or did I misunderstand?
@Edward, so if you take a separate test, then everything is fine, but in the code, for some reason, it gives the wrong data, well, maybe I did something wrong.
@ Sender1050 Well, if it works separately, but does not work in your code, then either you did not correctly indicate the source data in the first post, or you make a mistake in your version.
