Description

The wp_create_user function allows you to insert a new user into the WordPress database. It uses the $wpdb class to escape the variable values, preparing it for insertion into the database. Then the PHP compact() function is used to create an array with these values. To create a user with additional parameters, use wp_insert_user().

Usage

 <?php wp_create_user( $username, $password, $email ); ?> 

Example

As used in wp-admin/upgrade-functions.php:

$user_id = username_exists( $user_name );
if ( !$user_id and email_exists($user_email) == false ) {
	$random_password = wp_generate_password( $length=12, $include_standard_special_chars=false );
	$user_id = wp_create_user( $user_name, $random_password, $user_email );
} else {
	$random_password = __('User already exists.  Password inherited.');
}
