PHP template engine for loops

Question

I have a simple template engine that works fine the simple template, but I don't know how to adapt it to make it work with loops :

class Template {

   public $template;

   function getFile($file) {
      $this->template = file_get_contents($file);
   }

   function set($tag, $content) {
      $this->template = str_replace("{".$tag."}", $content, $this->template);
   }

   function ouput() {
      eval("?>".$this->template."<?");
   }
}

That's the loop I want to parse and display:

{{#each Stuff}}
  {{Thing}} are {{Desc}}
{{/each}}

I dont want use any SMARTY or Twig engine. Any idea please?

check this blade template, this is used by a popular framework, Laravel. — Bhaumik Pandhi

You just need a syntax that you can read and do foreach. Example: for[space]var[space]in[space]original_var: you could explode [space] and then execute a foreach based on var and original var. — Marco

Ok, keep in mind this is just for learning purposes. You can't ask on SO for the whole code, you need to try and post question about your tries.

This code parse a string for a foreach and then executes it:

<?php
$var = array(2, 4);

$str = 'for i in var';
$a = explode(' ', $str);

foreach (${$a[3]} as $i => $value)
{
    echo $value;
}

Read this part from PHP docs to understand what i did.
