I would say it depends where you want to get a job. I think most start-ups would weigh you having a kick ass GitHub profile more than a Zend certificate.

It's an accomplishment and will only help you. Not much to lose. Also don't be afraid to look into cisco certificate, which may not be directly related to the job your applying for, but look really good on a resume and can give you a better overhead picture.
