Php foreach循环结合了两个值

Question

我的例子如下：

Array
(
    [0] => stdClass Object
        (
            [user_id] => 8
            [users] => 1
        )

    [1] => stdClass Object
        (
            [user_id] => 8
            [users] => 18,19
        )

)

我需要运行foreach循环并最终得到类似：

Array
(
    [0] => stdClass Object
        (
            [user_id] => 8
            [users] => 1,8
        )

    [1] => stdClass Object
        (
            [user_id] => 8
            [users] => 18,19,8
        )

)

这样[user_id]和[users]组合成[users]

你的foreach，

foreach( $arrObjects as $object ) {
    $object->users = $object->'users'.','.$object->user_id;
}

你应该首先弄清楚你将如何接近它并发布你试图解决问题的方法。
