constant errors using insights Facebook marketing api (php) – Facebook api

I get this error when I try to run my app locally via xampp. Just to note, I generated code using quick start from developers.facebook so there shouldnt be errors within the code itself.

Notice: Use of undefined constant STDOUT – assumed ‘STDOUT’ in C:xampphtdocsworkingvendorfacebookphp-ads-sdksrcFacebookAdsLoggerCurlLogger.php on line 83

I’m starting to suspect that I got the wrong files from the composer. or there might be a problem with my setup. The contents of my composer.json just before I ran composer.phar was

{
“require”: {
“facebook/php-sdk-v4” : “~5.0”,
“facebook/php-ads-sdk”: “2.10.*”
}
}

I’m going to attach the code below just in case you guys want to look at it as well. The only thing that I modified there is adding the app_id since it was not included from the generated code.

<?php
