A simple math function that computes the cardinal sine of a real number x. It computes the historical (unnormalized) cardinal sine by default, but if its second argument is set to SINC_NORMALIZED then it computes the normalized cardinal sine of x instead. A great complement to the math functions already available as part of the PHP Core.
