I need to parse a PHP script with eval() and I want it to echo content that is outside of <?php tags.

My code gives an error because it does not know what to do with stuff outside of PHP tags. How can I echo stuff that is NOT inside PHP tags so this does not break?
<?php
 

$code = '

	<h1>PHP Info</h1>

	<?php

	phpinfo();

	?>

	Done!

	';
 

eval($code);
 

?>

Hello,

In the above I removed the first "<?php".
 
Use the code exactly what it is
