i wanna make it multi ( if else if else if ..)

Hello Dear Friends,

say we have 2 lang (en,ar) which can be set by following code

if($lang == "en") {
include_once "lang/english/co_en.php";
}  else if($lang == "ar") {
include_once "lang/arabic/co_ar.php";
}

and

if($lang == "en")
   $language="english";
else if($lang == "ar")
   $language="arabic";

what if we added es,ru so we have 4 (en,ar,es,ru)

how then can we rewrite the above code in case of 4 ??

thanks in advance

I'd use a switch.

switch($lang) {
case 'ar':	
	$language="arabic";
	// run an include or whatever here...
break;
case 'es':
	$langauge = 'spanish';
break;
case 'ru':
	$language = 'russian';
break;
case 'en':
default:
	$langauge = 'english';
break;
}

if all of the files follow that same format, just do something like this:

$lang = 'ar';
$languages = array('en','ar','ru','es'); // add languages here
$file = (in_array($lang,$languages))? 'co_'.$lang.'.php' : 'co_'.$languages[0].'.php'; // change array elem to whatever you want as default
include_once $file;

thank you all for help
