Postcode help

[Big_Tex]

Could anyone help me with this problem I am new to PHP I have the postcode data working and it's telling me the distance between two postcodes but what I need to do is take the result e.g postcode A and postcode b= 94 miles take the 94 miles and multiply it by a set price per mile e.g 0.55p per mile to give me a total cost for the trip in PHP I have searched the internet with no result help!😕 😕

[rehfeld]

this is really basic math......

$distance = 94;

$cost_per_mile = 0.55;

$price = $distance * $cost_per_mile;

OK, I may be oversimplifying this, but what you're trying to do doesn't sound too tough...

$distance = 94;
$pricepermile = .55;

$totalcost = $distance * $pricepermile;
echo "$".number_format($totalcost, 2, '.', ',');

Let me know if this is what you are looking for. If not, you may need to give more detail, and/or code.

[edit - OK Rehfeld got the same thing out of your post as I did, so I don't feel so bad... 😉]

and postcode 2 and multiply it by my .55 per mile the script is below thank you for any help you can give me

Define the two postcodes you wish to determine the distance between

$pc1 = "SO41 0RJ";
$pc2 = "SO41 9BZ";

Determine the distance between the two and place the result in $res

$res = calc_distance( $pc1 , $pc2 );

if ($res)
echo "The distance between $pc1 and $pc2 is $res metres";
else
echo "Sorry, one of the postcodes you entered was invalid";

$c = sqrt($a + $b);
return round($c);
}

$distance = calc_distance( $pc1 , $pc2 );

The distance is already calculated for you... You just need to do the math to find the total cost:

# Determine the distance between the two and place the result in $res 
$res = calc_distance( $pc1 , $pc2 ); 

if ($res){ 
echo "The distance between $pc1 and $pc2 is $res metres<br />"; 

// Here we do the math
$totalcost = ($res * .55);

// Here we format the output and echo the results
echo "$".number_format($totalcost, 2, '.', ',');

}else{
echo "Sorry, one of the postcodes you entered was invalid"; 
}
