$exp_date = "2006-01-16";
$todays_date = date("Y-m-d");

$today = strtotime($todays_date);
$expiration_date = strtotime($exp_date);

if ($expiration_date > $today) {
     $valid = "yes";
} else {
     $valid = "no";
}

Thankyou, also do you know of any way I can add a month to the date from date('Y-m-d'); without having to explode it and go through if statements to make it add years instead of going to 13 etc. ???

if it goes to 13 the computer sense the date infraction and alters it to add a year and subtract 12 months

look at strtotime

 

<?php
$today = date("Y-m-d");
$next_month = date("Y-m-d",strtotime("+1 month",$today))
echo "Today is: ".$today."<br />Next month is: ".$next_month;
?>

Today is: 2008-07-20

Next month is: 1970-01-31

 

lol :S

oops because i didn't use a valid date in UNIX timestamp for the second parameter in my strtotime

try

<?php
$today = date("Y-m-d");
$next_month = date("Y-m-d",strtotime("+1 month",strtotime($today)))
echo "Today is: ".$today."<br />Next month is: ".$next_month;
?>

 

Putting today in the strtotime is not needed because default is the current time if no parameter is set, but I wanted to show u  can put one in.

Today is: 2008-07-20

Next month is: 2008-08-20  Thanks :-D
