The PHP date() function formats a timestamp to a more readable date and time.
A timestamp is a sequence of characters, denoting the date and/or time at which a certain event occurred.

Syntax
date(format,timestamp)



PHP Date() - Format the Date:


The required format parameter in the date() function specifies how to format the date/time.


Here are some characters that can be used:


d - Represents the day of the month (01 to 31)
m - Represents a month (01 to 12)
Y - Represents a year (in four digits)
A list of all the characters that can be used in the format parameter, can be found in our PHP Date reference.


Other characters, like"/", ".", or "-" can also be inserted between the letters to add additional formatting:



Example:


<?php
echo date("Y/m/d") . "<br />";
echo date("Y.m.d") . "<br />";
echo date("Y-m-d")
?>




Output will be.,


2009/05/11
2009.05.11
2009-05-11





PHP Date() - Adding a Timestamp

The optional timestamp parameter in the date() function specifies a timestamp. If you do not specify a timestamp, the current date and time will be used.

The mktime() function returns the Unix timestamp for a date.

The Unix timestamp contains the number of seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and the time specified.

Syntax for mktime():

mktime(hour,minute,second,month,day,year,is_dst)


Example:

<?php
$tomorrow = mktime(0,0,0,date("m"),date("d")+1,date("Y"));
echo "Tomorrow is ".date("Y/m/d", $tomorrow);
?>


Output will be.,
 
 Tomorrow is 2009/05/12
