Update item of json array

I have a json array

[{
    "sku": "5221",
    "qty": 1,
    "price": 17.5,
    "desc": "5395 - Replenish Natural Hydrating Lotion 3.5oz"
}, {
    "sku": "11004",
    "qty": 1,
    "price": 30.95,
    "desc": "150 - Q-Plus 16oz"
}]

i am getting this array inside $item php variable and decoding that array

$jsonDecode = json_decode($items, true);
echo 'before' . PHP_EOL;
print_r($jsonDecode);

foreach ($jsonDecode as $key => $obj) {
    if ($obj->sku == '11004') {
        $jsonDecode[$key]['qty'] = '5';
    }
}
print_r($jsonDecode);

now i want if sku is 11004 then qty of that index would be 5 . but after using above code i got same array with same qty for that index.

how can i do so Please Help.

try below solution:

$json = '[{
    "sku": "5221",
    "qty": 1,
    "price": 17.5,
    "desc": "5395 - Replenish Natural Hydrating Lotion 3.5oz"
}, {
    "sku": "11004",
    "qty": 1,
    "price": 30.95,
    "desc": "150 - Q-Plus 16oz"
}]';

$array = json_decode($json, true);
//print_r($array);

foreach($array as &$a){
    if($a['sku'] == 11004){
        $a['qty'] = 5;
    }
}

echo json_encode($array);

output:

[{
    "sku": "5221",
    "qty": 1,
    "price": 17.5,
    "desc": "5395 - Replenish Natural Hydrating Lotion 3.5oz"
}, {
    "sku": "11004",
    "qty": 5,
    "price": 30.95,
    "desc": "150 - Q-Plus 16oz"
}]
