function template($template, $data) {
extract($data);
ob_start();
include $template;
return ob_get_clean();
}
That's all you need to write a template engine in PHP, because PHP is a template engine. You write your templates like this:
<html>
<head>
<title><?=$title?></title>
</head>
<body>
<h1><?=$title?></h1>
</body>
</html>
And call them like this:
<?php
echo template("template.tpl", array("title" => "Hello, world!"));
?>
And you can combine them like this:
<?php
$content = template("content.tpl",
array("heading" => "Content heading",
"body" => "content body"));
echo template("container.tpl",
array("title" => "Hello, world!",
"content" => $content));
?>
