print (date ("l dS of F Y h:i:s A"));
print ("July 1, 2000 is on a " . date ("l", mktime(0,0,0,7,1,2000)));
      

It is possible to use date() and mktime() together to find dates in the future or the past.

Example 2. Date() and mktime() example $tomorrow = mktime (0,0,0,date("m") ,date("d")+1,date("Y")); $lastmonth = mktime (0,0,0,date("m")-1,date("d"), date("Y")); $nextyear = mktime (0,0,0,date("m"), date("d"), date("Y")+1);

Some examples of date() formatting. Note that you should escape any other characters, as any which currently have a special meaning will produce undesirable results, and other characters may be assigned meaning in future PHP versions. When escaping, bu sure to use single quotes to prevent characters like \n from become newlines.

Example 3. Date() Formatting /* Today is March 10th, 2001, 5:16:18 pm */ $today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm $today = date("m.d.y"); // 03.10.01 $today = date("j, g, Y"); // 10, 3, 2001 $today = date("Ymd"); // 20010310 $today = date('h-i-s, j-m-y, it is w Day z '); // 05-16-17, 10-03-01, 1631 1618 6 Fripm01 $today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // It is the 10th day. $today = date("D M j G:i:s T Y"); // Sat Mar 10 15:16:08 MST 2001 $today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:17 m is month $today = date("H:i:s"); // 17:16:17

To format dates in other languages, you should use the setlocale() and strftime() functions.
