Abstract: A multiple functional, foldable, and portable ladder comprises a plurality of ladder units 5, wherein the ladder unit has a supporting rod on the two sides thereof. Each supporting rod is foldable so that the ladder is expandable for upstanding or foldable so as to be carried and stored and be used in emergency. Thus the ladder is convenient in application and storage. Two supporting rods between two adjacent ladder units 5 are pivotally connected by pivotal shafts, and two ends of each pedal are installed with respective control seats. A pivotal shaft and a movable buckling rod are installed within the control seat. Thereby, when the ladder is expanded, the supporting rod of the ladder unit is assembled by the control seat, during folding, the supporting rods are folded after the buckling rods has been displaced.
