ini_set() has been disabled for security reasons

I am using Laravel 5.1

I uploaded my project on a shared host. Everything was going well but one day when i try to browse the site a warning message appeared

Warning: ini_set() has been disabled for security reasons in /home/zamzamtransport/public_html/root/vendor/vlucas/phpdotenv/src/Dotenv.php on line 45

and

Warning: ini_set() has been disabled for security reasons in /home/zamzamtransport/public_html/root/vendor/vlucas/phpdotenv/src/Dotenv.php on line 47

I google for the solution everybody suggest me to upload my own php.ini. So, I did the following:

1. Create a new php.ini file in root directory.
2. Edit the file and write disable_functions=.
3. Edit my .htaccess and append this line suPHP_ConfigPath /home/zamzamtransport/public_html/

After doing this I have another error message Fatal error: Class 'PDO' not found in /home/zamzamtransport/public_html/root/config/database.php on line 16

I realize that the hosting provider can solve it by configuring their server, I just need to contact with them.

But, I want to know is there any way to solve it from my side?
