Please help me

Hi there,

I'm having trouble trying to do something similar to the website www.foxrentacar.com on the part to calculate the rates...

This is the code:
<?

if (($dropoff_array[day] - $pickup_array[day]) == 0) {

$days = 1;

} else {

$days = ($dropoff_array[day] - $pickup_array[day]);

}

$total = $days * $pickup_array[car];

echo $total;

But when I select the pickup date like May 29 and the dropoff date like June 04 it returns a invalid result...

I hope somebody can help me.

Thanks.

if (($dropoff_array[day] - $pickup_array[day]) == 0) {
$days = 1;
} else {
$days = ($dropoff_array[day] - $pickup_array[day] != "0");
}

sorry, ignore both my posts, my php coding in both posts was poor example & its time for me to go to bed, hope someone helps ya 🙂

why don't you convert all of your pickup and dropoff dates to timestamps using strtotime() or mktime() and then do the math. You can easily calculate the number of days by dividing by 86400 (the number of seconds in a day).

Thanks devin,

Could you give some example how to do it?I've never done something like this before and I have no idea how to do it.

Thank you

$pickup=mktime(0,0,0,5,29,2002);
$return=mktime(0,0,0,6,4,2002);
$period=$return-$pickup;
$days=$period/86400;
echo $days;

Ok, i'm going to assume the dates are in standard MySQL format (2002-05-31). Let's say the pickup date is May 13th and the dropoff day is June 3rd:

<?
$pickup_date = '2002-05-13';
$dropoff_date = '2002-06-03';
$price = '36.00';

$pickup_timestamp = strtotime ($pickup_date);
$dropoff_timestamp = strtotime ($dropoff_date);

$length = ($dropoff_timestamp - $pickup_timestamp) / 86400;

$total = $length * $price;

echo "
pickup date: $pickup_date<br>
dropoff date: $dropoff_date<br>
length: $length days<br>
price: $$price<br>
total : $$total
";
?>

Obviously this is a simple example, you'll have to tweak depending on how the date and price data is coming into the script.
