替换stdClass对象数组中的值

Question

I've been looking for a while and I can't find a way to get this to work. How can I replace values in a stdClass Object array? For example if I have this:

Array ( 
    [0] => stdClass Object (
            [id] => 1 
            [fruit] => 100
            [vegetable] => 200
        ) 
    [1] => stdClass Object (
            [id] => 2
            [fruit] => 100
            [vegetable] => 100
        )
    [2] => stdClass Object (
            [id] => 3
            [fruit] => 200
            [vegetable] => 200
        ) 
)

How do I change the values - fruit 100 to apple, fruit 200 to peach, vegetable 100 to broccoli and vegetable 200 to lettuce - I need to end up with this:

Array ( 
    [0] => stdClass Object (
            [id] => 1 
            [fruit] => apple
            [vegetable] => lettuce
        ) 
    [1] => stdClass Object (
            [id] => 2
            [fruit] => apple
            [vegetable] => broccoli
        )
    [2] => stdClass Object (
            [id] => 3
            [fruit] => peach
            [vegetable] => lettuce
        ) 
)

Thanks in advance for any help!

Answer 1

A stdClass Object is not an array, its an object so you need to use object notation:

$array[0]->id = 'foo';

read here Objects

Answer 2

Lets $array be your array, then:

$array[0]->fruit = 'apple';
$array[0]->vegetable = 'lettuce';

$array[1]->fruit = 'apple';
$array[1]->vegetable = 'broccoli';

$array[2]->fruit = 'peach';
$array[2]->vegetable = 'lettuce';

Answer 3

You can try

$fruit = array(
        100 => "apple",
        200 => "peach"
);
$vegetable = array(
        100 => "broccoli",
        200 => "lettuce"
);

$final = array_map(function ($v) use($fruit, $vegetable) {
    $v->fruit = $fruit[$v->fruit];
    $v->vegetable = $fruit[$v->vegetable];
    return $v;
}, $arrayObject);
