从instagram主题标签中获取数据属性

Question

I want to fetch data(the images in each post) stored in https://www.instagram.com/explore/tags/selfie/?__a=1, but all I get when I decode and var_dump this is NULL.

$obj = json_decode("https://www.instagram.com/explore/tags/selfie/?__a=1", true);
var_dump($obj);

Answer 1

You're trying to json_decode the STRING

https://www.instagram.com/explore/tags/selfie/?__a=1

What you need to do is to fetch the URL first. I suggest using file_get_contents, which takes a URL and returns the contents at the end of that URL.

Try this:

$json = file_get_contents("https://www.instagram.com/explore/tags/selfie/?__a=1");
$obj = json_decode($json, true);
var_dump($obj);
