title: Obtain the next times (in VARCHAR) from the DB in PHP, according to time now
body: <p>i have this mysql table with the timetables the train with <strong>php</strong>, </p>
  
  <pre><code>Type (INT) | time_start | time_stop
    1        |  09:31:00  | 09:34:00
    1        |  09:43:00  | 09:47:00
    1        |  09:55:00  | 09:58:00
    1        |  10:07:00  | 10:10:00
    1        |  10:33:00  | 10:36:00
    1        |  10:45:00  | 10:47:00
    1        |  10:57:00  | 11:00:00
    1        |  11:12:00  | 11:15:00
    1        |  11:35:00  | 11:38:00
  </code></pre>
  
  <p>(and it goes on..) 
  - "type" is the timetable type, cus it changes in the winter, summer, etc.
  - "type" is INT, and "time_start" and "time_stop" are VARCHAR(8)</p>
  
  <p>I would like to know the most efective way to get the 6 next "train times", acording to the time now.
  Imagine, it's now 09:33:10, what I want to obtain is this ones:</p>
  
  <pre><code>  1        |  09:43:00  | 09:47:00
    1        |  09:55:00  | 09:58:00
    1        |  10:07:00  | 10:10:00
    1        |  10:33:00  | 10:36:00
    1        |  10:45:00  | 10:47:00
    1        |  10:57:00  | 11:00:00
  </code></pre>
  
  <p>If theres any change change i should do in the mysql table, i'm also open to your ideias.
  Thanks in advance ;)</p>
