如何根据PHP中的键值合并/组合/插入2个不同的数组

Question

I need to merge 2 different kinds of array based on the same key value 1st Array:

Array{
 [0]=>Product{
  [name]=>car
  [type]=>honda
 }
 [1]=>Product{
  [name]=>motorbike
  [type]=>suzuki
 }
 [2]=>Product{
  [name]=>superbike
  [type]=>audi
 }
[3]=>Product{
  [name]=>car
  [type]=>suzuki
 }
}

2nd Array:

Array{
 [0]=>Seller{
  [name]=>andy
  [handle] =>car
 }
 [1]=>Seller{
  [name]=>davies
  [handle] =>superbike
 }
 [2]=>Seller{
  [name]=>kevin
  [handle] =>motorbike
 }
}

Final Output:

 Array{
     [0]=>Product{
      [name]=>car
      [type]=>honda
      [seller]=>kevin
     }
     [1]=>Product{
      [name]=>motorbike
      [type]=>suzuki
      [seller]=>kevin
     }
     [2]=>Product{
      [name]=>superbike
      [type]=>audi
      [seller]=>davies
     }
    [3]=>Product{
      [name]=>car
      [type]=>suzuki
      [seller]=>andy
     }
    }

So from the example array and the output that i given. I m trying to merge 2 different arrays into 1. Array 1 is the list of numerous product while Array 2 is the list of seller name and info. I m trying to assign each product according to the seller handle.

Therefore im trying to merge 2 different arrays based on the key value which is product[name] and seller[handle] to produce the final output as shown above

Here's a pretty standard approach:

$result = array();

foreach ($sellers as $seller) {
    // For each seller, loop through products and 
    // check if the name matches the sellers handle
    foreach ($products as $product) {
        if ($product['name'] == $seller['handle']) {
            // When a product has a name that matches the seller's handle, 
            // add it to the result array 
            $result[] = array(
                'name' => $product['name'], 
                'type' => $product['type'], 
                'seller' => $seller['name']);
        }
    }
}
