How to get json data without api - php

Question

I'm trying to get the viewer count so I can check if a streamer is online on https://www.dlive.tv/. If you view the page source on a streamer's page (https://www.dlive.tv/thelongestchain), there's a bunch of json and "watchingCount" is there.
Basically, I want to have the streamer appear on the "Live Now" section of my site if their viewer count is 1 or more, but I can't figure out anyway on how to get the viewer count. I know I could use something like Selenium if I was using python and could run it from my pc, but I need the site to know it.
DLive doesn't have an api yet, so I don't know how to make a call(or request I don't know the terminology) to get this info. When I look in the network tab on chrome I see that there's a call (https://graphigo.prd.dlive.tv/) that provides stream info I think. Would I also need my authkey?
I realize this question is broad and all over the place but it's because so am I with me trying to solve this the last couple days. If I had the viewercount as a variable, I know how to display the streamer on the "Live Now" section of my site, I just don't know how to get the necessary data.
If there's another way I should be checking if a streamer is online or offline other than getting the viewercount, that would work too. If anyone could help me out I would greatly appreciate it, thanks.
I tried scraping the page but I don't think you can scrape dynamic content. When I tried to use SimpleHTMLDom it just returned static elements.
<?php
require 'simple_html_dom.php';
$html = file_get_html('https://www.dlive.tv/thelongestchain')
if(($html->find('video', 0))) {
echo 'online';
}else{
echo 'offline';
}
/* The video element is only on the page if the streamer is live, but it doesn't return because it's not static I presume */
?>
I have no idea at all how to go about making a call/request to get the json data for the viewer count, or how to get any other data that could check if a streamer is online. All the scraping I've done did not return any elements that weren't static (the same no matter if the streamer was online or offline).

Answer 1

Try cURL, it's like a magic wand.
This will return the entire page, and I think including the JSON you're looking for:
<?php
$curl = curl_init('https://www.dlive.tv/thelongestchain');
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($curl);
var_dump($result); // you do as you need to here
curl_close($curl);
?>
Here's the <script> containing the data I believe you need. Assuming "watchingCount" is the same thing you're looking for?

I assume you'll then just have to throw in a loop and make the url dynamic to get through whatever streamers you're monitoring with your site.
