Re: HELP HELP on a file parser

Fixed a couple of things in the code. Pretty good for psudo code. :) But I get this error when running.

I can't test it.

I need some help, I think this is probably really simple and I was

wondering

if anyone had some code I could use to help me write this. I need a page to parse a text file with a list of numbers, and then

take

those numbers and parse another file with over 7MB of information

and to

look for those numbers and then to pull out the matches. Now the

file

that

its looking through each record that has a number in it is in a

specific

format with a beginnning and an end.

Can you give a short example of each file and what you want to match in each? ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
