Putting text into an array

[TheChief]

Hey, I need help with putting the following into an array:

"1, 45, 4642, 567" (no quotes)

I need the above to be put into an array, so $array[0] = 1, $array[1]=45 and so on.  The above text can contain more than 4 numbers...so loop will need to be used, and the number of commas counted.  Id appreciate it if someone could help me, as I don't know anything mabout arrays.

Thanks.
