[PHP-DB] Example of mail()

[Renzo Clavijo]

Hi all.
  
  In the code bellow you'll find an easy to use example of mail(). 
  
  I know it's very simple but the question is: How can I erase the values  held 
in $_REQUEST such that when I press F5 or I click "Reload" there  are no 
messages sent again?
  
  Thanks a lot for your help.
  
  
  Best Regards
  
  
  RENZO CLAVIJO
  
  PD: Please forgive me if my english is not OK
