PHP code gets commented out

Question

I have the following problem within the following script

PHP code:

$var = file_get_contents('template/default/index.php');
$content1 = str_replace('{php}','<?php',$var);
$content2 = str_replace('{/php}','?>',$content1);
echo $content2;

template/default/index.php code:

<!DOCTYPE html>
<html>
    <body>
        <h1>My First Heading</h1>
        <p>My first paragraph.</p>
      {php} echo 'worked'; {/php}
    </body>
</html>

I'm trying to transform the {php}{/php} tags within the template/default/index.php to propper php tags. This actually happends, but the php code gets commented out. The browser gives this in return:

<h1>My First Heading</h1>
<p>My first paragraph.</p>
<!--?php echo 'worked'; ?-->

Does anybody know how to solve this?

check the **template/default/index.php** content; the comment must be there. — Kneel-Before-ZOD, Aug 08 '13 at 13:39
Echoing the PHP like that isn't going to execute it, it would just send the PHP code to the browser, which will just display it. I would guess the Apache or PHP engine is commenting out the PHP code when you echo it. You'll need to either include the file or use the eval function. — Joshua Dwire, Aug 08 '13 at 13:39

Instead of echoing out the replaced content, it should be eval'd. Although I don't recommend that.

And how would I do that? Can;t figure it out with eval. Thanks for helping! – Aug 08 '13 at 13:44

or use include, and capture via php output buffers: `ob_start(); include($file); $contents = ob_end_clean();` – Daniel W. Aug 08 '13 at 13:49

I see no reason to do any of this.

Just use <?php and ?> in your index.php file instead of {php} and {/php} and then just include the file in your script.

I think he's trying to eval it like a template file similar to how Smarty template engine does it – Kieran Aug 08 '13 at 13:43
