Fatal error fatal error when writing PHP paging

Fatal error:cannot redeclare Htmtocode () (previously declared in D:\www_local\mytest\conn.php:7) in D:\www_local\mytest \conn.php on line 10
This error message appears when you write the paging file page.php
Google Translate this sentence means "Fatal error: Cannot re-declare Htmtocode ()"
The code for line 10th is

Connecting to a database
Include ("conn.php");
Introduction of Paging class files
Include ("page.class.php");
?>
Search on the Internet, the possible reason is: two page program file references cause a conflict when the memory is repeatedly loaded
Workaround: Replace include with Include_once ()

The above describes the fatal error to write PHP page fatal error resolution, including the content of the fatal error, I hope the PHP tutorial interested in a friend to help.
