date checking

[The Eerie Network]

Hi all, I want to write a function that will check a date given in yyyy-mm-dd format, and then see how many days have gone since that date, could someone help me with this please? I'm completly useless when it comes to adding up and subtracting dates, thank you

What you need to do is make PHP display the date in it's numeric format, like 2001-09-25. Then you will be able to seperate those numbers and be able to subtract date you want.

I will give it a swing for you when I get home. I don't have the means to try it out here on school .

Thank you, it's the whole 28,19,30,31 days in a month that screws me up

just incase you re interested it's going to be used to check the status of links in a directory portal, and display a NEW image if they are new

After seeing his code, I am certain mine will not work . I will still try to pull it off, we'll see. Mine looks much to simple compared to his.

The Eerie Network, I would like to advice you to use freddy's solution .

-Edit-

Please go with freddy's solution, my attempt only produces a total gibberish of numbers.

Hi, I take it that you are talking about this:

<?

    function date_compare($date1, $date2, $delim) {
        $t1 = explode($delim, $date1);
        $t2 = explode($delim, $date2);
        $tu1 = mktime(0,0,0,$t1[0], $t1[1], $t1[2]);
        $tu2 = mktime(0,0,0,$t2[0], $t2[1], $t2[2]);
        return ceil(($tu1 - $tu2) / 86400);
        }
    print date_compare("07-10-01", "06-10-00", "-");

?>

, the only problem with this is that I need 4 figure years, and from what I can see this uses 2 figure, do you know if this can be modified?

Mark - Thank you for trying.

You don't have to do anything withit except make the year 4 digits mktime() can use a two digit year or a 4 digit year.

    function date_compare($date1, $date2, $delim) {
        $t1 = explode($delim, $date1);
        $t2 = explode($delim, $date2);
        $tu1 = mktime(0,0,0,$t1[0], $t1[1], $t1[2]);
        $tu2 = mktime(0,0,0,$t2[0], $t2[1], $t2[2]);
        return ceil(($tu1 - $tu2) / 86400);
        }
    print date_compare("07-10-01", "06-10-00", "-"); //prints 395
    print "<br>";
    print date_compare("07-10-2001", "06-10-2000", "-"); //prints 395
