title: Adding 10 minutes to a date from mysql datetime and comparing it to the time now
body: <p>I can't figure out how to add 10 minutes to a time I am getting from mysql database the field structure is datetime.</p>
  
  <p>Current code </p>
  
  <pre><code>$nowtime = date('Y-m-d h:i:s');
  
  $timeoflastlogin = $db-&gt;gettime();
  
  //ADD 10 MINS TO TIME LAST ATTEMPTED 
  $endtime = strtotime('+ 10 minutes', $timeoflastlogin );
  //$endtime = date('Y-m-d h:i:s', strtotime('+ 10 minutes', $timeoflastlogin );
  </code></pre>
  
  <p>This displays "
      2011-09-07 13:53:43 &lt; time of last login
      2011-09-07 03:56:15 &lt; now time
      2611&lt; endtime - this is supposed to be time of last +10 mins "</p>
  
  <p>I cannot work out how to add 10 mins to the time/date from mysql, I need to do this and then set a command to compare the time now and of last login so if it has been 10 minutes I can stop the user trying to login again!</p>
  
  <p>Thanks for your help</p>
