I want to add up the corresponding prices.

Question

I want to reassemble the following array for each management_code, class_type.

$varArrayA = array(
    array(
        "manegement_code" => "1",
        "class_type" => array('A','B','C')
    ),
    array(
        "manegement_code" => "2",
        "class_type" => array('A','B','C')
    ),
    array(
        "manegement_code" => "3",
        "class_type" => array('A','B','C')
    )
);
$varArrayB = array(
    array(
        "manegement_code" => "1",
        "class_type" => "A",
        "price" => "200"
    ),
    array(
        "manegement_code" => "1",
        "class_type" => "B",
        "price" => "300"
    ),
    array(
        "manegement_code" => "1",
        "class_type" => "B",
        "price" => "300"                        
    ),
    array(
        "manegement_code" => "2",
        "class_type" => "B",
        "price" => "300"                        
    )
);

*I want this result

$varArrayB = array(
    array(
        "manegement_code" => "1",
        "class_type" => "A",
        "price" => "200"
    ),
    array(
        "manegement_code" => "1",
        "class_type" => "B",
        "price" => "600"
    ),
    array(
        "manegement_code" => "2",
        "class_type" => "B",
        "price" => "300"
    )
);

I made it as follows
I'm confused about incorporating conditions in class_type.
I would appreciate it if you could be a professor.

foreach ($varArrayA as $i => $varValueA) {
    foreach ($varArrayB as $rowow ){
        if($rowow['manegement_code']==$varValueA['manegement_code']){
            $varArrayC[$i]['manegement_code'] = $rowow['manegement_code'];
            $varArrayC[$i]['class_type'] = $rowow['class_type'];
            $num = $num+$rowow['price'];
            $varArrayC[$i]['price'] = $num;
        }
    }
}

$varArrayAをどう利用しているかわかりませんが・・・

$varArrayC = array_map(function($x,$y){
return array_merge(json_decode($y,JSON_OBJECT_AS_ARRAY),["price",$x]);
},$temp=array_reduce(array_map(function($x){
return [json_encode([
"manegement_code" => $x["manegement_code"],
"class_type" => $x["class_type"],
]),(int) $x["price"]];
},$varArrayB),function($x,$y){
if(!isset($x[$y[0]])) $x[$y[0]]=0;
$x[$y[0]]+=$y[1];
return $x;
}),array_keys($temp));
print_r($varArrayC);
