Colin Viebrock has posted this new item on his blog today with a patch for PHPAdsNew to integrate mysqli support.
PHP5 introduced support for an enhanced MySQL 4.1 library called MySQLi. If you’ve compiled in MySQLi support into your copy of PHP, then you should use the newer, more efficient MySQLi functions to access the database.
Here is a quick patch for users of PHPAdsNew who are running their site on PHP5 and MySQL 4.1.
You can download the patch directly from his website...
