I'm testing my script in PHP 5.5, works perfectly until I switch from MySQL to MySQLi.

Error:

Stack trace:

#0 C:\xampp\htdocs\url_rewrite.php(52): tep_db_fetch_array(NULL)
#1 C:\xampp\htdocs\url_rewrite.php(106): transform_uri(Array)
#2 [internal function]: wrap_href(Array)
#3 C:\xampp\htdocs\url_rewrite.php(12): preg_replace_callback('/(<[Aa][ ???]{1...', 'wrap_href', '<!DOCTYPE html>...')
#4 [internal function]: callback('<!DOCTYPE html>...', 9)
#5 {main}

Line 52 of url_rewrite:

$cat_Q = tep_db_query("select c.categories_id, cd.categories_name from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.categories_id = '" . $value . "'  and c.categories_id = cd.categories_id");

I'm not sure what I should be doing differently here. As mentioned, the script works without issue on MySQL.
Any help would be greatly appreciated!

I have tried relentlessly to use the proper code/quote syntax, but the forum keeps telling me it's incorrect. Sorry. :(

I went ahead and fixed your code. We don't use BBCode around here like most other forums do. Instead, we use the Markdown syntax. There's a link to documentation in the top right of every editor. Or it's here: http://www.daniweb.com/community/syntax

Are you sure that you have MySQLi installed??

Yes MySQLi is installed, I just upgraded a different script to MySQLi using the same folder space.

Aww :(

Any help at any time of the day is more than appreciated. Goodnight! :)

After some additional digging, ob_start appears to be the culprint (used for URL rewrite). Perhaps something in the code is incompatible with MySQLi? Any way to pinpoint the source of the incompatibility?
