 > @apedog well, select 1 might be good also, i am not SQL master, you
 might adopt that. Just found in internet, that the method i posted is
 fastest among others, however, you can tell your thoughts.

 > @SergeyBiryukov  thanks, but the $default option is not even related to
 this ticket. the ticket is about "existence" of option (nevertheless it's
 value, let it be string, boolean, or whatever, even no-one knows what
 value specific option might have, string, bool, or whatever). So, your
 offered one is not related to the problem directly, and doesn't solve it.

 @SergeyBiryukov is correct and the default option actually does the work
 that you're willing to achieve with your custom function. The $default
 option is just like your return value for the existence i-e: you're
 returning 'boolean' while $default in
 [https://developer.wordpress.org/reference/functions/get_option/#parameters
 get_options] is allowing us to set 'string' something to return if option
 doesn't exists.
