Answer 1

Try. Thats greater than or equal to 14 days.

 if($timenow >= $days_time){
     mail( $users_email, $subject, $emailbody, $headers);
    echo "email sent!";
 }

Also SELECT * is bad practice. You should only select the fields you need in that query.

Answer 2

I recommend doing the date comparison in SQL, instead of pulling back all of the data in your query:

SELECT * FROM accounts WHERE DateDiff(Now(), fourteendays) > 14

Also, what is in that column in the database? If it is a timestamp, why don't you just call it as such? Am I missing something?

Answer 3

I assume you have already set the '$timenow' variable somewhere previous in the script and I would make sure to check that both time formats are the same when comparing. That was my problem in the past.

Answer 4

Or even

SELECT * FROM accounts WHERE fourneendays < (NOW() - INTERVAL 14 DAYS);

I am assuming that NOW() gives the timestamp you want - it won't be in UTC (But you knew that, right)?
