How can I read a txt file line by line?
I have a .txt file which I am reading with php (fread). I want to print each line separately (so I can write a function to print only specified lines). How do I do this? How can I read this file line by line?
Also, if I have a delimiter, how can I put each field between the delimiters in its own array?
Any help on this will be much, much appreciated! Thanks!
If you use file() to read the file, then you will have an array of lines which you can loop through (via foreach()) or call specific line via the array index.

I agree. This is the way to do it if you are trying to read a file "line by line" since file() automatically splits on line returns. It can really help to simplify your code since you would not have to fopen() or fclose() the file.

as far as the delimeters to get the fields to another array, uisng the explode() function within the foreach loop mentioned above may help facilitate that.

We do precision guesswork
Hmm... could anyone point me to some cample code I could use to accomplish this?
Thanks, I think I got it though.
