Narrative:

After landing on runway 7R in phoenix; we were told to hold short of 7L. After several minutes; I believed I heard the tower clear aircraft Y; a B737 for takeoff on runway 7L. Shortly after that; a clearance was given for aircraft Z; another B737; to cross 7L. After that; we were given clearance to cross 7L. Having believed I had heard a takeoff clearance for 7L [aircraft Y]; I took extra time to clear for aircraft on departure roll. I noted that aircraft Y did appear to be on takeoff roll; I held short of the runway at taxiway F8. Aircraft Z crossed [runway 7L] downfield when the tower controller realized he had given conflicting clearances. Aircraft Y was told to cancel takeoff clearance. We were told to hold short of 7L; which was not a problem. Aircraft Z cleared the active runway; and noted they had gotten red runway incursion lights half way across the runway as they were crossing.
