A couple of projects ago I needed the ability to have international users. I looked for some php functions that would make the task of registering users a little easier. I found some html lists and turned them into php functions that return arrays

**

function getAustralianTerritories()
{
    return array('Australian Capital Territory' => 'Australian Capital Territory', 'New South Wales' =>
        'New South Wales', 'Northern Territory' => 'Northern Territory', 'Queensland' => 'Queensland',
        'South Australia' => 'South Australia', 'Tasmania' => 'Tasmania', 'Victoria' => 'Victoria',
        'Western Australia' => 'Western Australia');
}
