Question

我对这个问题感到很疯狂如何做一个反复返回slug值的foreach。

这是我的数组：[{"id":1,"catid":"digital-art","scategory":"3-Dimensional Art","slug":"3-dimensional-art","created_at":"2014-01-29 12:17:21","updated_at":"0000-00-00 00:00:00"}]

print_r返回：

Array
(
    [0] => stdClass Object
        (
            [id] => 1
            [catid] => digital-art
            [scategory] => 3-Dimensional Art
            [slug] => 3-dimensional-art
            [created_at] => 2014-01-29 12:17:21
            [updated_at] => 0000-00-00 00:00:00
        )

)

Answer 1

根据您的新评论更新：

根据您的新print_r，您的数据已经采用JSON对象格式，因此无需再次解析（jsode_decode()将失败）。

假设您的对象名称为$data，您可以通过以下方式访问其数据：

foreach ($data as $item) {
            echo $item->{'slug'};
            echo $item->slug;//same thing
}

希望这有帮助！

Answer 2

这不是一个“数组”，而是一个JSON格式化的String。你我用

将它解析成一个数组

$myArray = json_decode('[{"id":1,"catid":"digital-art","scategory":"3-Dimensional Art","slug":"3-dimensional-art","created_at":"2014-01-29 12:17:21","updated_at":"0000-00-00 00:00:00"}]', true);

最后一个参数指示将其转换为关联数组：

Array
(
    [0] => Array
        (
            [id] => 1
            [catid] => digital-art
            [scategory] => 3-Dimensional Art
            [slug] => 3-dimensional-art
            [created_at] => 2014-01-29 12:17:21
            [updated_at] => 0000-00-00 00:00:00
        )

)

这会迭代

foreach ( $myArray[0] as $key => $value ) { ...
