How would I check if a date in the format \"2008-02-16 12:59:57\" is less than 24 hours ago?
There should be you variable date Like
$date_value = "2013-09-12";
$Current_date = date("Y-m-d"); OR $current_date_time_stamp = time();
You can Compare both date after convert date into time-stamp so :
if(strtotime($current_date) >= strtotime($date_value)) {
echo "current date is bigger then my date value";
}
OR
if($current_date_time_stamp >= strtotime($date_value)) {
echo "current date is bigger then my date value";
}
