We will now learn how to manipulate dates in various formats and how to display them.

Code to use with the date() function:

Format	Description	Example
a	"am" or "pm" lowercase	pm
A	"AM" or "PM" uppercase	PM
d	day of the month	01 /20
D	day of the week with 3 letters	mon
F	month's name	January
h	hours (12 hours format)	12
H	hours (24 hours format)	08
g	hours (12 hours format)	4
G	hours (24 hours format)	10
i	minutes	44
j	day of the month	3

M	month of the year with 3 letters	oct
n	month of the year	4
s	seconds	30
y	year 2 numbers	08
Y	year 4 numbers	2008

Example: today's date:

 <?php
$today_date = date("m-d-Y");
print 'We are on '.$today_date;

//Out put on the screen 
?>
We are on 10-08-2008

System date format:

Example with the time() function

<?php
$today_date  = time();
print 'date system of today is '.$today_date;

//output 
?>

date system of today is 1012566581

Codes to use with the getdate() function:

key	description	Example
seconds	seconds	30
minutes	minutes	5
hours	day's hours from 0 to 23	15

mon	year's month	4
year	year with 4 numbers	2002
yday	year's day from 0 to 365	180
weekday	name of the week	Monday

Example with getday():

<?php $time = time(); // the date system format
$date = getdate($time); // passage of the time() variable via getdate() to get the info print 'We are on '.$date['mon'].' - '.$date['mday'].' - '.$date['year'].' it is '.$date['hours'].':'.$date['minutes'];
