  while timestamp is optional and specifies a timestamp. Default value
  for timestamp is current date and time */
 
  #Some characters that are commonly used for dates are:
  
  l (Lowercase L) - Represents day of the week
  d - Tells the day of the month
  m - Tells the month of the year
  Y - Represents a year

  echo "Today is " . date("m.d.Y") . "<br>";
