title: Incorrect table name, php/mysql
body: <p>I've got this code </p>
  
  <pre><code>        mysqli_query ( $userdatabase,
          'CREATE TABLE `user_'.$emailreg.'` (
          ID int NOT NULL AUTO_INCREMENT PRIMARY KEY,
  
          IP varchar(10),
          FLD1 varchar(20),
          FLD2 varchar(40),
          FLD3 varchar(25),
          FLD4 varchar(25),
          FLD5 varchar(25) )' );
  
          echo ( mysqli_error ($userdatabase) );
  </code></pre>
  
  <p>that works fine on my localhost, but when I upload it to the server, it starts giving me a "Incorrect table name 'user_vasya@rossya.pu'" error. any idea?</p>
  
  <p>Thanks!</p>
