Dates mess with my head!

[techmeister]

G'day folks:

I want to find out what the latest date is from a list of dates but have no idea how to go about it!

I have a function that returns the last modified dates of all the files in a directory and displays them on another page. I would like to display 'modified' next to all the files that have been modified within a specific time period, say 7 days.

Can anyone help me do this?
Many thanks!

To compare dates you should use mktime().
Read manual and ask one more question if somethins will be unclear.
This is example from date() manual page:
$tomorrow = mktime (0,0,0,date("m") ,date("d")+1,date("Y"));

So, seven days after today:
$days = mktime (0,0,0,date("m") ,date("d")+1,date("Y"));

Now, if you want to compare "26.06.2001" with this date, you should write like this:

$compare_date=maketime(0,0,0,6,26,2001);
if ($days>$compare_date)
{//compare_date is earlier...}

Hope, it is not necessary to write how to extract "6", "26" and "2001" from "26.06.2001" :-)

We have a function that we use on http://www.alt-php-faq.org to display a "new" next to questions edited/added within the past 7 days.

The function is :-
function time_difference($then,$difference)
{
list($year,$month,$day)=split('-',$then);
$then = mktime (0,0,0,$month,$day,$year);
$now = time();
$diff = $now-$then;
$days = ($diff - ($diff % 86400)) / 86400;
if($days<=$difference)
{
return true;
}else
{
return false;
}
}

its called as in
if(time_difference($date,7))
{
}

$date being the date the question was edited, in the format of
2001-06-25, if the difference is less then 7 it returns true

It might help
