FATAL ERROR - PHP Curl

Question

Notice: Undefined offset: 0 in C: Users aprendiz151ciee Desktop PHP - Webserver root DASHBOARD file.php on line 62

Fatal error: Maximum Execution time of 30 Seconds exceeded in C: Users aprendiz151ciee Desktop PHP - Webserver root DASHBOARD file.php on line 145

Does anyone know why you made a mistake?!
At home it works perfectly, arrives at the company... This mistake happens. It must be because at home I use XAMPP with PHP 7.1 and here at work I use the USB WEBSERVER?
