I've installed the latest versions of XAMPP (1.7.3) and ZendStudio 8 (18.104.22.168)
When I try to debug my scripts with ZendStudio, it generates the following warning for the mysqli_connect() method:
Headers and client library minor version mismatch. Headers:50145 Library:50018
It sounds like I may have different versions for my PHP executable and mysqli extension.
This build of XAMPP is using PHP Version 5.3.1
If I check out the PHP executables available to use in ZendStudio (preferences->PHP->Debug), the nearest match is PHP 5.3.3(CGI). I think this mismatch may be the cause of the error. Can anyone confirm and if so, does that mean manually reinstalling PHP rather than being able to use XAMPP?
