Search for User by Email Address

Searches for a WordPress user account by email address. Will return the name of the site if found.

\$user = get_user_by( "email", "[email protected]" );
if ( \$user ) {
    \$site = get_home_url();
    echo "Found user on \$site";

echo -n "$php_code" > hunt_user_by_email.php
