  /* This answer is about date and time
 
  The syntax for date and time is:
  */
 
  date(format,timestamp)
 
  /* Here, format is required and it specifies the format of the timestamp,
  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>";
  echo "Today is " . date("m.d.Y") . "<br>";
  echo "Today is " . date("m-d-Y") . "<br>";
  echo "Today is " . date("l");
  
  #Some characters that are commonly used for time are:

  H - 24-hour format of an hour (0 to 23)
  h - 12-hour format of an hour (0 to 12)
  i - Minute with leading zeros (0 to 59)
  s - Seconds with leading zeros (0 to 59)
