Let's say I have a PHP file (index.php) that displays another PHP file (info.php) within a textarea using file_get_contents() function. Is it possible to define some sort of tags in info.php so that index.php will only get the content between those tags?

For example, let's say info.php is like the following:

PHP Code:
// Some PHP code here...
Content I want to display...
// Some PHP code here...
Is there a way to get only the content between display tags or something like that?
