Join Keith Casey for an in-depth discussion in this video Solution: Apply the table data gateway pattern, part of PHP: Design Patterns.
- In this particular solution, I decided to use…Zend's TableGateway, just as we did in the earlier example.…My goal in this case was to minimize the code…that we actually had to change in index.php.…For example, Zend's normal TableGateway doesn't…implement a method called loadAll, or loadByID.…So I decided to write my own.…It's slightly more code to maintain,…but this will help us keep our interfaces the same.…So we look at the PostGateway,…you can see there's the constructors we'd expect,…just as we had before, and then here are…the two methods that I added.…
loadAll, which just calls select, and loadById,…which calls select with an additional parameter.…Like I said, these are just syntactical sugar.…They're not necessary to the solution,…and you probably don't have them,…but they might make life easier for the rest of your team.…
