如何在wordpress中创建用户时指定用户ID?

How can I specify my own user ID when inserting a new user in wordpress?

Looking at this page here: http://codex.wordpress.org/Function_Reference/wp_insert_user

It doesn't give me an option to specify the user ID of the user I want to insert into wordpress.

How would I be able to specify the User ID then?

The user id ( ID ) in wordpress is auto-increment field, you cant specify it while adding new user, if you add it then update will be done matching the user id rather new insert, like:

$user_id = 10;
$somevar = 'test';
wp_insert_user( array ('ID' => $user_id, 'user_dat' => $somevar) ) ;

Since ID is provided here, the user id with value 1 will be updated, if matching ID is found.
