4. E_NOTICE : Run time notice.

5. E_CORE_ERROR : errors that occur during PHP's initial
startup.

6. E_CORE_WARNING : Warnings (non-fatal errors) that occur
during PHP's initial startup.

9.E_USER_WARNING : User-generated warning message.

10. E_USER_NOTICE : User-generated notice message.

11.E_STRICT : Run-time notices. Enable to have PHP suggest
changes to your code which will ensure the best
interoperability and forward compatibility of your code.
