Is codeigniter fine for my web application?

Some of you may of seen my poll I recently created which you can see the result for here:
PHP poll results

Now that the poll has ended and I've got a good idea on the top 5 frameworks (not just from the poll I carried out) I'm considering using codeigniter. I have worked with the Zend Framework but only as a web designer for implementing the static xhtml & css so I'm familiar with the file structure and admin controller but nothing more than that. Because I'm not advanced at PHP, at the moment I only know enough to be able to create a PHP website that queries an SQL database to retrieve content information. So I'm thinking the Zend framework may not be suitable because it seems to target advanced developers and people have mentioned its documentation is "scattered". Anyways based on the project requirements above would codeigniter be fine for the task?
