Where to put functions / classes?

[eluser]meigwilym[/eluser]

so would I have function getphone in the mobile.php file (in the controllers folder)?

Yes (but as it's a class call them 'methods' to save any misunderstandings).

Also I presume the $1 refers to the parameter that getphone will accept?

Yup. You should have

Code:

public function getphone($phone_name) {
// code here
}

In the above case $phone_name would be HTC-Desire.
