The collapse scenario of a scalar field along with a perfect fluid distribution was investigated for a conformally flat spacetime. The theorem for the integrability of an anharmonic oscillator has been utilized. For a pure power-law potential of the form , it was found that a central singularity is formed which is covered by an apparent horizon for and . Some numerical results have also been presented for a combination of two different powers of in the potential.
