I have migrate an app from a localserver with XAMMP to a hosting service, I'm using some functions of PHP 5.5 than are not supported by 5.3, My hosting had PHP 5.3, I configured it to 5.5 then this happens when trying to connect to mysql database with PDO
SQLSTATE[HY000] [2002] No such file or directory
What do I have to configure to correctly connect to MYSQL and make my app run
