Please help with date comparison

[kmazumdar]

I have a date accepted in form and build the date as follows

$delivery_dt =$deliveryYear."-".$deliveryMonth."-".$deliveryDay." ";
$delivery_dt .=$deliveryHour.":".$deliveryMinute.":"."00";

Now I have to validate $delivery_dt which should fall between my order receive date ( retrieved from a mySQL db stored as datetime datetime ) and sysdate.

Which function should I use to do the comparison ?

Thanks

I'm not sure about this, but I'd try

if( strcmp($delivery_dt, $receive_date) > 0 )
  if( strcmp($delivery_dt, date("correct time format")) < 0)
  echo "validation ok";

I'm not sure about the less and greater than values, try switching them if it doesn't work.
