Template-Fehler!

[Deathrow]

Hallo @ all!

Warum funktioniert meine Template-Klasse denn cniht?:

<?
class MobileTemplate {
var $file; var $sub; var $hpt;

function MobileTemplate($file){
$tmpl = fopen($file, 'r');
$tpl = fread($tmpl, filesize($file));
fclose($tmpl);

function def($sub, $hpt){
$tpl = str_replace($sub, $hpt, $tpl);
}

function show(){
echo $tpl;
}
}
}

if(!$name) $name = "Bitte den String <b>name</b> verwenden!";

$a = new MobileTemplate("tpl.htm");
$a->def("%NAME%",$name);
$a->def("%COPYRIGHT%", "Copyright (C) 2003 by [url]www.123-Mobile.de.vu[/url]");
$a->show();
?>

weil er innerhalb deiner Klasse deine tpl Variable nicht kennt

class MobileTemplate{
    var $tpl;

    function MobileTemplate($file){
        $tmpl = fopen($file, 'r');
        $this->tpl = fread($tmpl, filesize($file));
        fclose($tmpl);
    }
    function def($sub, $hpt){
        $this->tpl = str_replace($sub, $hpt, $this->tpl);
    }

    function show(){
        echo $this->tpl;
    }
}
