Getting data from your perch_form

Hi,

I really need help on this, I've created a custom form in perch, it is working fine, But I don't know how to retrieve the responses through Php, I do need to show all responses in a table style, but the response are in JSON.

or do I just need to use json_decode of php ? and retrieve the data using mysql ? isn't there any function in perch that can do just that .

Thank you and God Bless,
