you're echoing out php tags &lt;?php, , presumably displaying in browser. look php code in browser, because browsers render &lt; < it's not php code. it's text.

php not recursively executable, e.g.

<?php    echo "<?php echo 'foo '; ?>"; ?>

would echo out <, ?, p, etc..., not foo.

you can stuff 

<?php      $foo = "<?php echo 'hello world!'; ?>";     file_put_contents('hello.php', $foo); ?>

without issues. long file you're producing gets executed php (e.g. don't name "hello.html"), php not know (or care) script produced other php code.
