In the wild Phals grow down not up. So your plant leaning is just a normal growth pattern. Left to itself it will eventually grow straight down.
You can remove the plant straighten it and refill the potting mix to get it straight again. If you do be careful as Phal roots are thick and brittle. If you bend them too far they crack. Cracks are a possible source of rot, but Phals are strong plants and usually take re-potting easily.
