Answer 1

This error means that your might have logical mistake in your code.

Function strpos returns int|false.

See details about this warning in official documentation:

Warning: on may return Boolean false, but may also return a non-Boolean value which evaluates to false. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

This means that you need to check result of strpos like !== false before using result.
