从PHP数组中获取图像

Question

我正在尝试从数组的子数组中获取图像并显示正确的大小。我已设法将子数组存储到变量中，但似乎无法抓取图像。 我想输出[media_url]和[thumb]尺寸。

这是通过print_r（）输出的数组：

Array
(
    [0] => stdClass Object
        (
            [id] => 81223091856078976
            [id_str] => 81223091856078976
            [indices] => Array
                (
                    [0] => 0
                    [1] => 23
                )

            [media_url] => http://pbs.twimg.com/media/C0Wft4WEAACVt_.jpg
            [media_url_https] => https://pbs.twimg.com/media/C0Wft4WEAACVt_.jpg
            [url] => https://xxxxxxx.com
            [display_url] => pic.twitter.com/xxxxxxx
            [expanded_url] => https://twitter.com/xxxxxxx/status/8122309393021504/photo/1
            [type] => photo
            [sizes] => stdClass Object
                (
                    [medium] => stdClass Object
                        (
                            [w] => 1108
                            [h] => 784
                            [resize] => fit
                        )

                    [thumb] => stdClass Object
                        (
                            [w] => 150
                            [h] => 150
                            [resize] => crop
                        )

                    [small] => stdClass Object
                        (
                            [w] => 680
                            [h] => 481
                            [resize] => fit
                        )

                    [large] => stdClass Object
                        (
                            [w] => 1108
                            [h] => 784
                            [resize] => fit
                        )

                )

提前致谢

你可以这样做： -

$arr[0]->media_url
$arr[0]->sizes->thumb->w
$arr[0]->sizes->thumb->h
$arr[0]->sizes->thumb->resize

注意： - 如果您使用的是foreach()，请从所有人中删除[0]。
