Keywords: Multiple, Language, PHP, $HTTP_ACCEPT_LANGUAGE
I'm just shooting this one up here for the Archives.
Since I could not find a built in PHP function to access the preferred languages on a
user I came up with this.
The original version acted as a http server in that you needed to have a different
file for evey language (ie. index.php.en, index.php.fr, index.php.de).
I find that's a complicated way to work since if you need to update code you will have
to do it in several files.
I prefer simply
if (phpLang_current == 'fr') {
print "Ceci est francais";
} else (
// default to english
print "This is english";
}
If it's a large block of text you can have seperate include text files as in.
if (phpLang_current == 'fr') {
include("mytext.fr");
} else (
// default to english
include("mytext.en");
}
So in case anyone else ever needs this... Here it is...
