4096

[gizzmo]

hi
can someone dumb this out for me:
$fd = fopen ("/tmp/inputfile.txt", "r");
while (!feof ($fd)) {
$buffer = fgets($fd, 4096);
echo $buffer;
}
fclose ($fd);

in the script above what does the 4096 stands for. I've been using for for a while and never know exactly what it means.

Much appreciation for this site and the folks who replies.

Thanks, Gizzmo.

read the first 4 kb (= 4096 bytes)

Thanks Sid

Now, what would happen if that number were to be lowered or raised. would it still return line or part of a line, I guess what I'm having a hard time understanding is how comes, with that number it always return lines all the way to the end?.

Thanks, again (I'm learning)

if you have a line longer that 4 kb it should cut it off. the 4096 are mainly a prevention to not use too much time and resources to read incredibly long strings as far as i understood it.

Thanks sid, that makes perfect sense. I learn something new today.

Thanks,Gizzmo
