Another graceful way to do the same:
PHP Code:
<?php
$banner['default'] = 'default-banner.jpg';
$banner['AU'] = 'au-banner.jpg';
$banner['DE'] = 'de-banner.jpg';
$banner['US'] = 'us-banner.jpg';
$country_code = getenv(GEOIP_COUNTRY_CODE);
if (isset($banner[$country_code]))
{
$banner['default'] = $banner[$country_code];
}
echo ('<img src="' . $banner['default'] . '" alt=""/>');
?>
