I am trying out the YouTube data API V3 using PHP on a IIS web server (version 8.5.9600). I followed the instructions provided, installed the PHP code samples, API client library using composer, and setup the developer API key etc... https://developers.google.com/youtube/v3/code_samples/php
When trying out the search function on the PHP code samples, it returns a blank page.
I did the same but with a XAMPP installation with Apache web server (version 2.4.25) and it works fine. The problem is when I use the IIS web server. The code is exactly the same since I just copied the files, the PHP version is also the same PHP 7, I also tried with PHP 7.1. The web servers are installed on a Windows 8.1 machine.
I would really love to know how I can make the YouTube API work under PHP in IIS.
