Question about reading files

[Anon]

How would you read a certain line from a text file?

Like, i want to make a script that reads the first 25 lines of a text file, tells the user how far it has got, uses a meta-refresh and continues doing the next 25 lines, tells the user how many of X records it has done and proccesses next 25 lines etc.

Could someone please tell me how to do this?

I have searched through php documentation on filesystem and found nothing

Any help would be greatly appreciated.
thanks,
Laurece
