Question

I am writing password recovery code that uses a token and a date stored in date("Y-m-d H:i:s") format e.g. 2012-09-06 18:59:53. I use the code below to check if the token key for a user id exists:

$sql = mysql_query("SELECT * FROM `recoveryemails` WHERE `UserID` = '$uid' and `Key` = '$key' and `expDate` >= '$curDate'");

I need to add another condition after retrieving the expDate to check whether it’s older than 3 days, using PHP. Can anyone help me out with that PHP code?

Answer 1

It’s a lot easier in MySQL: WHERE ... AND expdate >= DATE_SUB(NOW(),INTERVAL 3 DAY)

But if you insist on doing it in PHP, you will need:

$threedaysago = strtotime("-3 days");
$expdate = strtotime($row['expDate']);
if( $expdate >= $threedaysago) { /* more recent than three days ago */ }
