title: PHP date of birth checker
body: <p>I am currently using the following PHP code to check date of birth, the code uses the american mm/dd/yyyy although I'm trying to change it to the british dd/mm/yyyy.</p>
  
  <p>I was hoping someone could tell me what to change:</p>
  
  <pre><code>function dateDiff($dformat, $endDate, $beginDate)
  {
      $date_parts1=explode($dformat, $beginDate);
      $date_parts2=explode($dformat, $endDate);
      $start_date=gregoriantojd($date_parts1[0], $date_parts1[1], $date_parts1[2]);
      $end_date=gregoriantojd($date_parts2[0], $date_parts2[1], $date_parts2[2]);
      return $end_date - $start_date;
  }
  
  //Enter date of birth below in MM/DD/YYYY
  $dob="04/15/1993";
  echo round(dateDiff("/", date("m/d/Y", time()), $dob)/365, 0) . " years.";
  </code></pre>
