I created a small ZendFramework based project using localhost (php 5.3).
After the completion and full checkups of the application, the customer later provided the server with php 5.2.9.
This means, my PDO based scripts do not run on the server, and there is no chance to upgrade PHP on the server.
How can I alter my application codes and make it run on this server environment?
I guess PDO is only the problem, but there may be more issues.
