我目前正在开展一个项目,在这个项目中,用户的关注者会在一个类似于此处的数组中提供给我:http://pastebin.com/304iPm4L
阵列:
object(stdClass)#2 (3) {
["pagination"]=> object(stdClass)#3 (2)
{
["next_url"]=> string(146) "DATA"
["next_cursor"]=> string(13) "DATA"
}
["meta"]=> object(stdClass)#4 (1)
{
["code"]=> int(200)
}
["data"]=> array(9)
{
[0]=> object(stdClass)#5 (4)
{
["username"]=> string(7) "twurked"
["profile_picture"]=> string(106) "https://igcdn-photos-g-a.akamaihd.net/hphotos-ak-xaf1/t51.2885-19/11055444_697242820403478_108851570_a.jpg"
["id"]=> string(9) "307611076"
["full_name"]=> string(20) "#twurked For Reposts"
}
[1]=> object(stdClass)#6 (4)
{
["username"]=> string(12) "itsmarziapie"
["profile_picture"]=> string(107) "https://igcdn-photos-b-a.akamaihd.net/hphotos-ak-xfa1/t51.2885-19/10735354_634448103338889_1219780551_a.jpg"
["id"]=> string(9) "415505158"
["full_name"]=> string(15) "Marzia Bisognin"
}
[2]=> object(stdClass)#7 (4)
{
["username"]=> string(11) "briankgrubb"
["profile_picture"]=> string(107) "https://igcdn-photos-d-a.akamaihd.net/hphotos-ak-xpa1/t51.2885-19/10518270_1508565329429347_713909002_a.jpg"
["id"]=> string(8) "28307611"
["full_name"]=> string(11) "Brian Grubb"
}

}
}

我要做的是获取每个用户的username
值并将其输出到屏幕。
所以,我想到的是我可以很容易地(或者我认为......)遍历我的结果并在每个嵌套数组中输出username
值。
我使用了这段代码:
$i = 1;
while ($i <= 10) {
$instagram->getUserFollows('self',10)->data[$i]["username"];
echo "<br/>";
$i++;
}
$instagram->getUserFollows('self',10)
数组,就是你在pastebin中看到的。通过查看我的嵌套数组,我似乎需要一个数字,然后["username"]
才能访问每个用户名。
理论上,$instagram->getUserFollows('self',10)->data["1"]["username"];
应输出itsmarziapie
然而,当我运行上面的代码时,我得到了这个:
Cannot use object of type stdClass as array
这个错误是什么意思,为什么我不能将我的username
数据循环到屏幕上?
此时,我已经进行了大约2.5小时的故障排除,现在我正在寻找你们的指导。我知道有很多关于相同错误的问题,但是没有一个包含像这样的嵌套数组,所以我有点迷失。
感谢您帮助我指出正确的方向:)
答案 0 :(得分:2)
您可以使用:
//You request 10 objects but you don't know if there are really 10
$info = $instagram->getUserFollows('self',10);
//How many objects?
$qty = count($info->data);
/* You can't assume that there are 10 objects (I refer to your code,
* you have 9 objects and you try to access to 10 objects)
*/
for($i = 0; $i < $qty ; $i++) {
echo $info->data[$i]->username . "<br>";
}
