I would not recommend turning down the error reporting level. This might
lead to unexpected behaviour in your application and makes it hard to back
track errors.
Always develop with error reporting set to E_ALL. You may set a lower level
for your production environment and disable the display of errors:
ini_set('display_errors', 0);
