问题
I'm having a bit of a problem here.
I insert a date into the database: date_last_applied
.
I can just call this by using $row['date_last_applied']
, of course. Now, I need to check if this inserted date was 30 days ago and if so, execute an action.
$query = "SELECT date_last_applied FROM applicants WHERE memberID='$id'";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
$date = strtotime($row['date_last_applied']);
}
That's about all I have.. I tried some things, but they all failed. :(
回答1:
if ($date < strtotime('-30 days'))
If you are only performing actions on dates older than 30 days, you should use Marco's solution.
回答2:
You could do it via SQL getting only dates in last 30 days
SELECT date_last_applied
FROM applicants
WHERE memberID = your_id
AND date_last_applied BETWEEN
DATE_SUB(NOW(), INTERVAL 30 DAY) AND NOW()
or older than 30 days
SELECT date_last_applied
FROM applicants
WHERE memberID = your_id
AND date_last_applied < DATE_SUB(NOW(), INTERVAL 30 DAY)
