I would recommend you to give Yii[0] a try. It is a solid, consistent and well thought framework with a vey good documentation. Unfortunately, It has always been eclipsed by new kids on the block frameworks like Laravel but really deserve more credits (provided you accept to let some of the laravel magic go).

I work for a web development company and We have been successfully using Yii for years now, including for medium size projects (in terms of LOC and exposure).

Just my two cents
