WP prepending e-mail with the word ‘Email’

Hello,

I have written a plugin to validate users by calling a java servlet and processing the response. I add new users to wp_users via wp_insert_user and update users via wp_update_user. All is well, except that the e-mail address is being prepended with the word “Email”.

Here’s the debug coded I added for a new user:

foreach ( $userarray as $key=>$value ) {
 echo '<br />'.$key.' '.$value;
}

RESULT:
user_login usernewtest10
user_pass secretpassword
first_name
last_name Besancon
user_url
user_email [email protected]
description 123456789
aim
yim
jabber
display_name usernewtest10

Then I execute this code:

if ($id = username_exists($username)) {
 $userarray['ID'] = $id;
 wp_update_user($userarray);
} else {
 wp_insert_user($userarray);
}
echo '<br />Has my e-mail changed??? '.$userarray['user_email'];

RESULT: Has my e-mail changed??? [email protected]

All good, right? Except the e-mail address has been stored as [email protected]. Since I can’t show you a screen shot of the admin screen, here’s some sql that shows the result:

select user_login, user_email
from wp_users
where user_login = 'usernewtest10'

RESULT:
user_login user_email
———- ———-
usernewtest10 [email protected]

Does anyone have any idea why this is happening? I checked the other plugins that were installed, and none of them appear to have anything to do with e-mail addresses.

Thank you in advance!
