Answer 1

使用array_filter：

$array = array_filter($array, function($x) {
    return $x['quantity'] != 0;
});

Answer 2

我认为它是PHP。

你可以这样做：

foreach($arr as $key => $value) {
    if($value['quantity'] < 1) {
        unset($arr[$key]);
    }
}

或

$arr = array_filter($arr, function($val) {
    return ($val['quantity'] > 0);
});
