RE: [PHP] Delimiter WITHOUT lots of IF's

Ralph, I tested the function below but the result at the page is: "CD Quantity: Array" and not the CD quantity according to file size... Why is the array there and what it is supposed to be called with to give one or another result? Thanks, Cesar Aracena www.icaam.com.ar > > Actually, I missed a few things on that function.
