Not to annoy you, but this will fail if a user has the preferred
languages in the order Dutch, French, English (which would be very
likely for a Belgian user). If you really want to deal with it
while totally respecting the user's wishes, you'd want to explode() the
string using ',', and analyze the given array in the right order:
// Available languages & user preferences.
$aLang = array('fr' => 'french.htm', 'en' => 'english.htm');
$aSett = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);
// Make sure that if no languages match, English is picked.
$aSett[] = 'en';
// Loop the user preference.
foreach ($aSett as $sLang) {
$sLang = substr($sLang, 0, 2);
if (array_key_exists($sLang, $aLang)) {
// Language found.
include $aLang[$sLang];
break;
}
}
