title: Getting total number of registered users
body: <p>In my app I have login/registration system and need to count the total number of registered users. For example I have 2 registered users.</p>
  
  <pre><code>----------------------------------------------------
  |id|    email      |use_name|user_pass|confirm_pass|
  ----------------------------------------------------
  |7 | theo@gmail.com|  theo  | my pass |   my pass  |
  ----------------------------------------------------
  |8 | test@gmail.com|  test  | my pass |   my pass  |
  ----------------------------------------------------
  </code></pre>
  
  <p>The is a function in mysql called SUM,but it adds ints.In my case though the id is incrementing from the last deleted user. </p>
  
  <p>Thanks,</p>
