[Help] - Substring Comma Delineated Values

I have a field in my database that has a potential value of x,y,z. I am looking for a way to go through and take out the x y and z and store them into separate strings. The problem is sometimes there is one value, other times two and then other times three.

It can have 0-3 values.

1: x
2: x,y
3: x,y,z

Can someone please help.

 

I was just told about the explode function. Problem solved.
