Yes, but that's a stylized phi (a big O with a diagonal slash), like the "is a member of" symbol is a stylized epsilon. The standard, Greek-style phi is often used for the golden ratio, 1.618... The letter tau is increasingly used in its place, though. Phi is also a very common name for certain kinds of functions, especially homomorphisms. Finally, the capital phi (a circle with a vertical line down the middle) is used for an important function in number theory involving the primes.
