this can be done via langauge files!
you may want to have a folder named 'languages' ,for example, and in it language files e.g. english.lng, arabic.lng, dutch.lng ...etc
these file will have variables that contains your text ,, like this:
PHP Code:
|
<?PHP
//note that you have to open php tags since it's not a php extension file !
$txt['main_welcome'] = 'Hi there !';
$txt['main_login'] = 'Please login!';
//etc ..
?>
|
of course you can change the names of the variables as you like ..
but it's preferable to use file name's inastead of just $txt, because when your site becomes large, you will reach 1000 which can be very annoying ! I ran into this problem and reached $txt[1004]!!
so instead ,as I said, call the vars with the file name like this:
PHP Code:
|
<?PHP
//main.php variables..
$main['welcome']='Welcome visitor';
$main['whatever']='whatever!';
//profile.php text variable..
$profile['posts']='Number of posts';
$profile['username']='Username:';
//and so on..
?>
|
now in all your script .. hava a function that will check the user langauge and include() the requested langauge file by user ,,
of course you have to use session or cookies for that !
maybe an intro page to let users choose their language or dropdown menu ,,
anyway here is a function that will check language :
PHP Code:
|
<?PHP
function check_lang() {
//make sure that we have a language selected by using session ..
if (!isset($_SESSION['lang'])) {
/* you can either show error message and terminate script
die('No language was selected! please go back and choose a langauge!');*/
//or set a default language
$lang = 'english';
} else {
$lang = $_SESSION['lang'];
}
//directory name
$dir = 'languages';
//no we return the langauge wanted !
//Returned String Format: dirname/filename.ext
return "$dir/$lang.lng";
}
?>
|
now in your script, this is how you use text from langauge files..
PHP Code:
|
<?PHP
//this function will check user language and return the file name to be included ..
$lang = check_lang();
include_once($lang);
//now this is how you print text
echo $txt['main_welcome'];
?>
|
so no matter what was the language the text will appear in its correct place ;)
but one note, all langauge files MUST have the same varibles names !! |
