My wording is a little vague b/c it's mainly a follow up to the question I linked (I didn't want to hijack that thread).
How can I process large files with while(<>)?
Briefly - he opened a file, read the file handle into an array, and processed the array with a foreach loop. The problem seemed to be that the file was too big to read entirely into an array. So the solution was to go line by line on the file with while<HANDLE>.
I haven't been using perl all that long. I learned to process files with the former method using foreach, and only recently learned about while<HANDLE>. That's why I'm asking when to use which.
