how to parse template file?

[PHPycho]

Hello forums!
I have some file named "test.tpl"
whic has following contents
"Hello %name% your passwrod is %passwrod%"
I would like to call this file and replace those values within % with dynamic values(may also {}).
Any comments and suggestions are warmly welcome.
Thanks in advance to all of you

$values['name']="John";
$values['password']="sex";
 
$text=file_get_contents("template.html");
$text=preg_replace("/\%([^\% ]+)\%/e","$values[$1]",$text);
print $text;
