如何使用foreach引用组合array1来匹配array2的id

Question

I have two arrays. array1 contains details of users and array2 has personal details. How do I merge array2 into array1 by using foreach reference?

$array1 = [
['id'=> 1,'name'=>'John Sena', 'lastname'=>'Jonn'],
['id'=> 2,'name'=>'Rock', 'lastname'=>'Rock Sena']
];

$array2 = [
['id'=>1, 'company'=>'Warner Brother'], ['id'=>2, 'company'=>'Metro'],['id'=>'1', 'Address'=>'USA']
];

Answer 1

You might use array_merge and in the second foreach use pass by reference for &$a1

$array1 = [
    ['id'=> 1,'name'=>'John Sena', 'lastname'=>'Jonn'],
    ['id'=> 2,'name'=>'Rock', 'lastname'=>'Rock Sena']
];

$array2 = [
    ['id'=>1, 'company'=>'Warner Brother'], ['id'=>2, 'company'=>'Metro'],['id'=>'1', 'Address'=>'USA']
];

foreach ($array2 as $a2) {
    foreach ($array1 as &$a1) {
        if ($a2['id'] == $a1['id']) {
            $a1 = array_merge($a1, $a2);
        }
    }
}

print_r($array1);

Result:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => John Sena
            [lastname] => Jonn
            [company] => Warner Brother
            [Address] => USA
        )

    [1] => Array
        (
            [id] => 2
            [name] => Rock
            [lastname] => Rock Sena
            [company] => Metro
        )

)
