I'm no programmer. I'd consider myself more of a designer and marketer. But I plan on creating a SAAS app soon and I was planning to use PHP for one main reason in that our billing system will be PHP (WHMCS) and our CMS will be php (WordPress). I think this is one of the advantages of PHP in that there is a lot out there already created in PHP. Is PHP really this bad that I should consider using something like ruby instead? My worries are finding good talent that want to work on a custom php application a few years down the road when we expand. And of course I'd want to be more likely to prevent bad code and build something that will be future proof. Thoughts? How screwed are new companies that start building php applications today?
