Former Accrington man Murphy, 26, will join on a two-year deal from Wycombe when his deal expires on 1 July.
Wildig, 23, was on loan with the Shrimps from Shrewsbury at the end of last season and has also agreed a two-year contract.

The trio join Tom Barkhuizen and Lee Molyneux as new arrivals at the Globe Arena this summer.
