I have string $str = "20090630|A|0.5
                                 20090630|B|0.7";
basically a file wiht 2 lines is read in to a string.
I want to output string in the format 20090630,0.5,0.7
Can this be done in one liner ?
I know we can split with "\n" first and then with "|" but i want to know if it can be done in one line ?

Thanks for your help
