convert webform date to oracle format
This is more of a PHP question, I believe, as you use PHP functions to accomplish this.

&lt;?php   
  $dob = $submission-&gt;data[11]['value'][0];
  $time = strtotime($dob);
  $oracle_format = date('d-m-Y', $time);
  // OR
  // $oracle_format = date('d-m-Y', strtotime($dob));
?&gt;


This uses the functions date() and strtotime()
