function date_calc_format in Date 5.2

Same name and namespace in other branches

1. 6.2 date_php4/date_php4_calc.inc \date_calc_format()
2. 6 date_php4/date_php4_calc.inc \date_calc_format()

Formats the date in the given format, much like strfmt()

This function is used to alleviate the problem with 32-bit numbers for dates pre 1970 or post 2038, as strfmt() has on most systems. Most of the formatting options are compatible.

Formatting options: <pre> %a abbreviated weekday name (Sun, Mon, Tue) %A full weekday name (Sunday, Monday, Tuesday) %b abbreviated month name (Jan, Feb, Mar) %B full month name (January, February, March) %d day of month (range 00 to 31) %e day of month, single digit (range 0 to 31) %E number of days since unspecified epoch (integer) (%E is useful for passing a date in a URL as an integer value. Then simply use date_calc_days_to_date() to convert back to a date.) %j day of year (range 001 to 366) %m month as decimal number (range 1 to 12) %n newline character (\n) %t tab character (\t) %w weekday as decimal (0 = Sunday) %U week number of current year, first sunday as first week %y year as decimal (range 00 to 99) %Y year as decimal including century (range 0000 to 9999) %% literal '%' </pre>

Parameters

int $day: The day of the month.

int $month: The month.

int $year: The 4 digit year. Do not add leading 0's for years prior to 1000.

string $format: The format string.

Return value

string The date in the desired format.
