Q. about calculating dates

Anon

Hello, I have used mktime before, but I have one question

I have a variable, such as:
$expire

And Date (Today's date)
$date = date("m d Y");

My question is determining if today's date is within a week of the expired date

I don't know how to calculate with mktime using variables. How would I do this? I can subtract 7 days from todays date, for instance, using mktime, but variables...no idea

Thank you

Well with all of PHP's time functions they operate in seconds, so the amount of seconds in 7 days is: 604800. To determine date ranges you would add or subtract that number to determine if a date is within the range.

mktime with variables in not a huge mess. You can check out PHP.net to get the specifications of that function but basically you pass it the time you want, broken into hours, minutes, seconds, day of the week, month of the year, and year and it spits back seconds since January 1, 1970. With that and the number above along with some code determining seven day intervals isn't all that difficult.

check out this page:

http://www.phpbuilder.com/manual/function.strtotime.php

use this function

$time1 = strtotime($expire);
$time2 = strtotime($date);

$time3 = $time1 - $time2;

if ($time3 < 604800) {
print "less than one week";
}else{
print "greater than one week";
}

hope this helps,
good luck!!

Sorry, but even though it should work, it doesn't

Let's say today's date is:
07-23-2002

And the expire table field is:
08-11-2002

IT will say to renew, when only dates 7 days or closer to the expire date should trigger that

I must be doing something wrong?

2 possibilities:

1.) you didn't convert the table info using mktime function in which case it is using the wrong date for comparison basis

2.) you are not using the mktime function properly, post your code and let's see...

Hello. Here is the code:
The idea is if Expire is 8 days or later than "date" value, it should say "Greater than one week" but if it is 7 days or less away from "Date" then it should say "Less than one week"

But it always says "Greater than one week" Feh...frustrating

Thanks

$expire = "10-26-2002";
$date = "10-25-2002";

$time1 = strtotime($expire);
$time2 = strtotime($date);

$time3 = $time1 - $time2;

if ($time3 < 604800) {
print "less than one week";
}else{
print "greater than one week";
}
