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。我已经设法将子数组存储到一个变量中,但似乎无法获取图像。 我想输出[media_url]和[thumb]大小。从PHP数组中获取图像
这里是通过print_r的阵列输出():提前
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
)
)

'$ arr [0] - > media_url'和'$ arr [0] - > sizes-> thumb-> w'和'$ arr [0] - > sizes-> thumb-> h'和'$ arr [0] - > sizes-> thumb-> resize' –
看起来像您的数组包含对象。对象方法和属性通过 - >运算符来访问。 – Loopo
