Help me create a PHP function that parses/converts the Content-type: multipart/form-data to Content-type: application/x-www-form-urlencoded.

SAMPLE INPUT IN PHP:

------WebKitFormBoundarylkP0tuzRBmvdHRcy Content-Disposition: form-data; name="email" test@mail.com ------WebKitFormBoundarylkP0tuzRBmvdHRcy Content-Disposition: form-data; name="password" testpassword ------WebKitFormBoundarylkP0tuzRBmvdHRcy-- Content-Disposition: form-data; name="terms" agree ------WebKitFormBoundarylkP0tuzRBmvdHRcy-- Content-Disposition: form-data; name="date" 12/31/2022 ------WebKitFormBoundarylkP0tuzRBmvdHRcy-- AFTER RUNNING THE CODE/FUNCTION I WOULD LIKE TO HAVE A OUTPUT LIKE THIS: email=test@mail.com&password=testpassword&terms=agree&date=12/31/2022
