enter zip code, calculate distance from my zip code

Is there a way to calculate distance from my zip code

by allowing user to enter their zip code in a text box

You will have to write something. Rather than reinventing the wheel, take a look at this.

You need a zipcode database with longitude and latitude coordinates. Then you have to calculate the distance between the two points.

This link below should help you it has a link to download a database and it has some sample code. Let me know if you still need help.

I added
x->query('90035');

comparing it with

$y->query('90210');

the output is
5190.44 kms

how can I change the code so a user can input their zip code
and outputs distance in miles

shobinsun

Hello,

Use this method:

$first = $_GET['distance1'];

$second = $_GET['distance2'];

x->query($first);

$y->query($second);

the $_GET['distance1'] and $_GET['distance2'] are the values entered by the user in a form.

Hello,

The error is because of the invalid entry of code or you have entered only one code in the user field.

Which code you have entered ?

10021 10001 generates 6114.18 kms
10021 90210 generates 7050.58 kms

is there anyway to convert kms to miles

shobinsun

Hello,

You can convert kms to miles in the code as:

$dist=$x->calcDistance($y, EyeGeoData::KMS, 2);
$dist=$dist/1.6093;
echo $x->calcDistance($y, EyeGeoData::KMS, 2) . ' kms';
echo $dist . ' miles';
