That's just it, I don't know how to 'read' each line and stop.... And the
first field is unique.... Sorry to be such a dummy, I'm still very new to
PHP, and have never really used Perl either ;)
By 'using a regular expression', do you mean that something as simple as an
"if" statement might do the job?
Can you help any further?
Thanks for getting me this far.
James.
