Pushing From Input To A Function?

Hey all,

I am making a simple little script to work out fuel econemy and I don't know how I can push the form data to a function which will make some calculations and then return it to the page.

How can I use the post data and then send it to a function as arguments?

I hope that makes sense, any help is much appreciated!

 

<?php
$data = $_POST['data']; // name of your field
function returnme($argument) {
      return $argument;
}
echo returnme($data); // we pass our $data as an argument
?>

PHP:

 

Might make more sense to you like this:

<?php

function returnme($argument) {
return $argument;
}

$data = $_POST['data']; // name of your field
echo returnme($data); // we pass our $data as an argument
?>

Also, when you define your function, you can set default values for the variable:

function returnme($argument=0) { // sets 0 as the default if no value is passed to the function
return $argument;
}

 

Awesome, I worked it out from the replies, thank you guys!

If you wanna see it I have it up here: http://www.gobbly2100.com/projects/fuel_econemy/

You might want to round numbers off to three digits.
