PHP Date Function
The php date function is great; i use it on virtually every website that I write, for example, the copyright text at the bottom of this page uses the date function to determine which year to stamp on it. The function is called quite simply by using:-
echo $date ;
So as you can see that will return :- 2009
If you scroll down the page it will show the various letters to put into the date() to give you various different displays.
echo $date ;
$date2 = date("D, d M Y H:i:s O");
So that will in turn give you : – Fri, 11 Dec 2009 21:58:57 +0000
‘r’ is the full description code for the same as referenced in $date2.
echo $fileupdated ;
This little line will give you the date that a file was last uploaded to your server. This function I use alot with a non-live pricelist website that can only be updated manually.
This example will give you the following : April 13 2009 22:56:06;
There are so many useful reasons to use the date function; for the best variation that you will need, browse down below to get a list of display types. The best thing to do is to try out a few combinations in a small php file.
