[RESOLVED] Need a more powerful str_replace()

[hadoob024]

I don't know why I'm blanking on this one. Basically, I have a string containing serial numbers. This string can have multiple newlines and carriage returns actually separating the serial numbers. I want to clean the string so that multiple newlines and carriage returns are removed. However, I still need to separate the remaining serial numbers with a comma. There isn't a consistent naming convention used, and there can be multiple occurrences of these carriage returns and newlines, so I can't just do something like:

str_replace("\r\n", "", $mystring)

or

str_replace("\r\n", ", ", $mystring)

So I need something like this:
V423060018
V311911037

-or-

V265141004

V265141004

V241889035

to be returned as:
V423060018, V311911037

-and-

V265141004, V265141004, V241889035

respectively.

Any thoughts?

/(\r?\n|\r)+/
