                                     date

   (PHP 3, PHP 4 )
   date -- Format a local time/date

Description

   string date ( string format [, int timestamp])

   Returns a string formatted according to the given format string using
   the given integer timestamp or the current local time if no timestamp
   is given. In otherwords, timestamp is optional and defaults to the
   value of time().

     Note: The valid range of a timestamp is typically from Fri, 13 Dec
     1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the
     dates that correspond to the minimum and maximum values for a
     32-bit signed integer). On Windows this range is limited from
     01-01-1970 to 19-01-2038.

     Note: To generate a timestamp from a string representation of the
     date, you may be able to use strtotime(). Additionally, some
     databases have functions to convert their date formats into
     timestamps (such as MySQL's UNIX_TIMESTAMP function).

   Table 1. The following characters are recognized in the format
   parameter string
   format character Description Example returned values
   a Lowercase Ante meridiem and Post meridiem am or pm
   A Uppercase Ante meridiem and Post meridiem AM or PM
   B Swatch Internet time 000 through 999
   d Day of the month, 2 digits with leading zeros 01 to 31
   D A textual representation of a day, three letters Mon through Sun
   F A full textual representation of a month, such as January or March
   January through December
   g 12-hour format of an hour without leading zeros 1 through 12
   G 24-hour format of an hour without leading zeros 0 through 23
   h 12-hour format of an hour with leading zeros 01 through 12
   H 24-hour format of an hour with leading zeros 00 through 23
   i Minutes with leading zeros 00 to 59
   I (capital i) Whether or not the date is in daylights savings time 1
   if Daylight Savings Time, 0 otherwise.
   j Day of the month without leading zeros 1 to 31
   l (lowercase 'L') A full textual representation of the day of the week
   Sunday through Saturday
   L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
   m Numeric representation of a month, with leading zeros 01 through 12
   M A short textual representation of a month, three letters Jan through
   Dec
   n Numeric representation of a month, without leading zeros 1 through
   12
   O Difference to Greenwich time (GMT) in hours Example: +0200
   r RFC 822 formatted date Example: Thu, 21 Dec 2000 16:01:07 +0200
   s Seconds, with leading zeros 00 through 59
   S English ordinal suffix for the day of the month, 2 characters st,
   nd, rd or th. Works well with j
   t Number of days in the given month 28 through 31
   T Timezone setting of this machine Examples: EST, MDT ...
   U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) See also
   time()
   w Numeric representation of the day of the week 0 (for Sunday) through
   6 (for Saturday)
   W ISO-8601 week number of year, weeks starting on Monday (added in PHP
   4.1.0) Example: 42 (the 42nd week in the year)
   Y A full numeric representation of a year, 4 digits Examples: 1999 or
   2003
   y A two digit representation of a year Examples: 99 or 03
   z The day of the year (starting from 0) 0 through 365
   Z Timezone offset in seconds. The offset for timezones west of UTC is
   always negative, and for those east of UTC is always positive. -43200
   through 43200

   Unrecognized characters in the format string will be printed as-is.
   The Z format will always return 0 when using gmdate().

   Example 1. date() examples
   <?php
   // Prints something like: Wednesday
   echo date("l");
   // Prints something like: Wednesday 15th of January 2003 05:51:38 AM
   echo date ("l dS of F Y h:i:s A");
   // Prints: July 1, 2000 is on a Saturday
   echo "July 1, 2000 is on a " . date ("l", mktime(0, 0, 0, 7, 1,
   2000));
   ?>

   You can prevent a recognized character in the format string from being
   expanded by escaping it with a preceding backslash. If the character
   with a backslash is already a special sequence, you may need to also
   escape the backslash.

   Example 2. Escaping characters in date()
   <?php
   // prints something like: Wednesday the 15th
   echo date("l \\t\h\e jS");
   ?>

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

   Example 3. date() and mktime() example
   <?php
   $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);
   ?>

     Note: This can be more reliable than simply adding or subtracting
     the number of seconds in a day or month to a timestamp because of
     daylight savings time.

   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, be sure to use single
   quotes to prevent characters like \n from becoming newlines.

   Example 4. date() Formatting
   <?php
   // Assuming 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, n, 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.
