Hi,
I'm trying to limit the amount of content retrieved with fgets when pulling
data from a url. I'm generating page extracts and only need the first 2K to
4K. What I'm finding is that when I limit fgets, I get NOTHING but run
within a while loop, I get the whole string.
What works:
//retrieve the page from the Internet
$file = @fopen ("$url", "r");
// bcg need to add error handling so if website is offline, page is
still logged and retrieved later
if (!$file) {
//log error
//need to write logging code
}
else {
//load the file into a string var
while (!feof ($file)) {
$string = $string . fgets($file, 4096);
}
}
What fails:
//retrieve the page from the Internet
$file = @fopen ("$url", "r");
// bcg need to add error handling so if website is offline, page is
still logged and retrieved later
if (!$file) {
//log error
//need to write logging code
}
else {
//load the file into a string var
while (!feof ($file)) {
$string = $string . fgets($file, 4096);
break;
}
}
I've done it with and without the while loop, tried if tests and such. Its
strange.
Thanks in advance
