This problem has also bothered me for a long time, until I found a very simple solution.

This problem is caused by a BOM character, which is used to tell code page and which endian is of a text file. When you include a PHP file, this character will be included as well. Although you will not see the BOM character, but it might cause gap on your page.

Using HTML comment mark to wrap php code which includes other php files. And the BOM character will be considered as comment and will not appear on page.
