So, you have your website in a template system? Are you "replacing" all those template variables? Don't want to do that? You want to replace them dynamically without doing something like:
$mytpl->replaceVar("LANGUAGE_HELLO_WORLD",$arrLang["english"]["LANGUAGE_HELLO_WORLD"]);
These files take a template, and replace all the LANGUAGE_* template variables with the ones found in a CSV file. This is EXTREMELY fast, a lot faster than the normal replace routine (find and replace).
(Note: I haven't tested the following script, so you might want to fix some code to make it work :\ However, I'm using this setup and it works really great)
This is an example template file: (index.tpl)
----------------------------------------------------------------------
<html>
<body>
{LANGUAGE_HELLO_WORLD}
</body>
</html>
This is the language file, in CSV (lang.csv)
----------------------------------------------------------------------
LanguageID;english;spanish;deutsch;
LANGUAGE_HELLO_WORLD;Hello world;Hello world in spanish;Hello world in deutsch;
And here is the class file that does the trick (lang.class.php)
----------------------------------------------------------------------
<?
class language {
var $intLangID;
var $arrLangDB = array();
function language() {
global $langid;
$this->intLangID = $langid;
// Open the language file.
$arrLanguageFile = file("lang.csv");
array_shift($arrLanguageFile);
// Loop it and create another array.
for($intA = 0; sizeof($arrLanguageFile) > $intA; $intA++) {
$arrThis = split(";",$arrLanguageFile[$intA]);
if(sizeof($arrThis) > 2) {
$strVarName = $arrThis[0];
array_shift($arrThis);
$arrLang["".$strVarName.""] = $arrThis;
}
}
$this->arrLangDB = $arrLang;
}
function getText($arrLangKey) {
$strLangKey = "LANGUAGE_".$arrLangKey[1];
return $this->arrLangDB["".$strLangKey.""][$this->intLangID];
}
function implementLanguage($res) {
$strText = preg_replace_callback('/{LANGUAGE_(.*?)}/',array($this,'getText'),$res);
return $strText;
}
}
?>
All you need to do in your template system is to call this when reading/parsing the template, e.g.:
$res = implode('',file('index.tpl'));
$res = $GLOBALS["objLanguage"]->implementLanguage($res); //make sure you have created the object objLanguage ($objLanguage = new language()
That's it....i'm sure I might have simplified it...but hey, you'll learn something! |

The following will do the trick also.
<?
$arrLang["English"]["LANGUAGE_HELLO_WORLD"] = "Hello world";
$arrLang["Danish"]["LANGUAGE_HELLO_WORLD"] = "Hallo world";
$arrLang["Icelandic"]["LANGUAGE_HELLO_WORLD"] = "Halló heimur";
// passing an associative array
$smarty->assign($arrLang["".$somedynamiclangvar.""]);
?> |
