Prior to Top of Descent we experienced a Low Pressure light on engine 1 hydraulics. We accomplished QRH and informed Maintenance [via] ACARS. Shortly after reporting we noticed intermittent lights on electric pump 1 and Flight Control A. System A read zero quantity and system pressure cycled between 0 and 2925 psi. This happened throughout descent; and upon leveling at 9000 MSL the light became steadier.We surmised a total loss of hydraulic system A and went back into the QRH. We coordinated with Approach Control for extended final visual to allow time for gear extension. Upon landing we extended the rollout to avoid excessive braking and side loading upon turnoff. We then parked awaiting inspection from Fire/Rescue. We were towed to gate. No reported passenger or crew injuries.

B737 flight crew reported loss of hydraulic system A fluid and pressure.
