Question

I am working on a simple template engine, and I was wondering if it’s feasible to include the template file multiple times, once for each time the template is rendered. It basically goes like this:

function rendering_function_in_rendering_class()
{
    include $path_to_templates . get_class($this) . 'template.php';
}

And then in the template file:

<h1>Hello, <?php echo $this->awesomename ?>!</h1>

This function does exactly what you need:

<?php

function embed($file, $vars) {
  ob_start();
  extract($vars, EXTR_SKIP);
  include($file);
  $content = ob_get_contents();
  ob_end_clean();

  return $content;
}

?>

It takes file path as a first parameter and key/value array of variables which will be extract into the scope such that your template will be able to use them directly in HTML like this:

<h1><?php print $title; ?></h1>
