Don't do that. The foreach reads the whole file into memory and then
walks it line by line. If we just want one at a time, let's fetch them
that way
I don't agree with this.
And I don't understand this. ;)
If you are working with a file that is as small as
the one included seems to be easier to just load up some data structures. I
understand writing efficient code is always best but for a quickie script
like this I wouldn't be to concerned with the 1/100th of a ms that your
going to shave off but not dumping the contents to memory.
If you're going to work with the lines one at a time anyway, what exactly is the advantage of using the probably slower and definitely more memory wasteful foreach()?
