Hi,
You shouldn't need to alter your include_path variable to include a file. Instead, you could include the file relative to your current one. Your file is in
/public_html/examples/fragments, but your functions.php file is in
/public_html. Therefore, you could use
require_once('../../functions.php'); to call your file in your script.
Alternatively, if you really want to change your include_path (though I would not recommend it), please try setting it to the full path (which starts with
/home/tlocx10h).
Thank you,
