php - 共通のキーを持つ 2 つの配列をマージする

Question

私は2つのJson配列を持っています:

$arrayA = array("avg" => '1',"shape" => 'hey');

$arrayB = array("avg" => '2',"shape" => 'trapezoid');

javascriptor asを使用してそれらを結合したいPHP：

arrayAB = {"avg":['1', '2'], "shape":[hey', 'trapezoid']};  

Answer 1

$arrayA = array("avg" => "234","shape" => "hey");
$arrayB = array("avg" => "5678","shape" => "trapezoid");
$array3 = array();

foreach ($arrayA as $key => $value) {
    $array3[$key] = array($arrayA[$key], $arrayB[$key]);
}
