By ordinairy counting would work?

edited from the function explication fgets
(http://www.phpbuilder.com/manual/function.fgets.php)

Example 1. Reading a file line by line

$i=0;

$fd = fopen ("/tmp/inputfile.txt", "r");
while (!feof($fd)) {
$i++;
$buffer = fgets($fd, 4096);
}
fclose ($fd);

Zack

whats the 4096? ive always used MySQl for databases, using flat files is new to me...

could you explain what it does step by step? at least comment in the code?

Have a look at the link I posted with it.

In short: you set a counter to zero ($i). Then you open a file (fopen()), and start reading from it, while you are not at the end of file (wile(!feof($fd)))
The 4096 has to do with the length of the string to be read. I am not sure why it is that number (I have not used the function myself). I'd suggest you try like this on a short file (say 100 lines), and perhaps alter the number here and there, and see what happens.

Good luck,

Zack

thanks
