Comment:

 Hi @farhan.noor, welcome to WordPress Trac!
 > For example, there is an option field 'test' exist in the option table
 but without any value(NULL or empty). Now `get_option('test', 'Hello
 World')`  function will return an empty string as it is; from the database
 but developer may be expecting "Hello World" in return.

 That seems like expected behavior to me. All scalar option values
 ultimately stored in a `longtext` field in the database, which means that
 they're retrieved as strings, and an empty string is a valid value. See
 the discussion in #31820.

 You could use the `option_{$option}` filter to perform a more strict
 check, see an example in comment:3:ticket:31820.

 [attachment:option.php] is not a proper patch, see the

 handbook entry on submitting a patch].
