Reading a line at a time from a file

[bjg]

Hey,

Just wondering what the best way to do this is?

What i specifically want to do is check if a user exists on a unix machine.
The best way i was told was to read a line at a time of /etc/passwd and
check if the username is in that line.

Cheers

system("grep <username> /etc/password") and process the result. Probably a
whole hella lot quicker on system with a large number of users and reading in
and having php parse and search the whole file.
