Escape Characters: Printing PHP

Hello,
I'm having a bit of trouble figuring out how to write php to a file. No matter how I escape it I get a slash before the closing > in the php tag..

PHP:

fwrite($profileFilePointer, "<?php require(‘./system/files/profile.php’); ?>" );

I've tried

PHP:

fwrite($profileFilePointer, "<?php require(‘./system/files/profile.php’); ?/>" );

and a few other ways of escaping, but nothing worked yet. lol.
thanks.
