如何解决PHP致命错误:类'COM'错误? 我无法在webhost中访问php.ini但它在WAMP中脱机工作

I'm running my first website online using hostinger.ph free web hosting. I'm having an error saying:

Fatal error: Class 'COM' not found in /home/u527002491/public_html/map.php on line 59  
[13-Sep-2016 09:45:18] PHP Fatal error: Call to a member function query() on a non-object in /home/u527002491/public_html/centralhomepage.php on line 79  
[13-Sep-2016 09:50:19]  

I need it to work for my SMS notification. I searched the web for hours and can only see answers about changing something in the php.ini but it's impossible to change that in hostinger.php.

I also found out about changing or adding something in the .htaccess file but I have no idea what to do.
