My 30months old son was diagnosed with cerebral palsy. he srill can't walk but he's undergoing physical therapy. is there a chance for him to walk?

Yes: We like to see a child achieve head balance by 9 months, sit by 24 months and crawl by 30 months to indicate a chance of walking. Also depends on the level of involvement how functional the gait will be.

Cerebral palsy: Cerebral palsy has a wide range of severity. Many children with CP are able to walk. It would be helpful to discuss the specifics of the nature of your son's cerebral palsy with your doctor. Depending on the nature and severity your son may require physical therapy, braces or aids, or surgical pricedures. I would recommend seeing an orthopaedic surgeon.
