fopen

Anon

$url = "http://www.website.com/index.html";
$file = fopen($url, "r");
fclose($file);

correct me if i am wrong but this would get the contents of website.com's index.html and put it into $file, so why am a presented with these errors:

Warning: fopen("http://www.website.com/index.html","r") - Bad file descriptor in main.dat on line 62

Warning: Supplied argument is not a valid File-Handle resource in main.dat on line 63

Warning: Supplied argument is not a valid File-Handle resource in main.dat on line 64

what is wrong?
Thanks

It must be that the web address is wrong, or the file you're trying to open does not exist, or the server is not responding.

The syntax you're using, works fine when I tried it just now to read my own website home page.

Anon

no i continue to get this error when trying to read from local or remote files, it may be a fault withmy webhost, any other suggestions?

Anon

The error that you posted suggests you are pointing at a nondeliverable page.

That could be due to any number of factors, including perhaps a block put in place by your ISP (if so, I would immediately change ISPs).

It's possible that your version of PHP was compiled with the "url wrapper" functionality disabled.

There also is a problem with the code you posted: it simply opens and closes the file, but does not read it.

$fd = fopen('http://www.phpbuilder.com/rss_feed.php?type=coding&limit=20','r');
$myfile = fread($fd, 12000);
fclose($fd);

Now up to 12000 bytes of an PHPBuilder.com XML file should be parked in $myfile.

Another, simpler way would be this:

$myfile = implode(file('', 'http://www.phpbuilder.com/rss_feed.php?type=coding&limit=20'));

... which fetches the remote file as an array of strings and then collapses it into a single string.

I got the same error. Maybe it's the ISP.. My site is hosted by Freedom2Surf, everything worked fine on my own machine (RH6.1 linux with apache, php4). But when i uploaded it to the server i got those errors.

I anyone want to look at the scripts:
http://www.dkb2.f2s.com/fopen.php

//**************source*****
<?php
$file = fopen("http://www.php.net/", "r");
if (!$file)
{
echo "<p>Unable to open remote file.\n";
exit;
}

while (!feof($file))
{
$line = fgets($file, 1024);

if (eregi("<title>(.)</title>", $line, $out))
{
$title = $out[1];
break;
}
}
fclose($file);
?>
//**********************end

You can look at phpinfo() at URL:
http://www.dkb2.f2s.com/test.php

If the problem lies at the ISP can you give other ISP's where it DOES work.

I believe that you helped a lot of people...

Thanks,
Mark

ps the script it from PHPBuilder.com

Anon

I've seen this similar problem with my own locally-hosted Apache server (and a PHP install from php4win.de); if I just refresh a couple of times it works... weeeeird.

Anon

Hey Mark

I got the samme errors also on my f2s hosting. If you ever find out whats wrong, please email me 🙂

Anon

Yes? what is your ISP? Free or not?

please inform us.

I've had no problems with fopen() on urls with two ISPs (plus my own self-hosted sites), using PHP3 and 4.

www.phpwebhosting.com is cheap and has no problems with fopen() on remote urls, but I have had some problems with other users abusing the system (tying up CPUs with bad code).

Anon

also have a site at freedom2surf, and am getting the same problems with a web-grab script that i know works on my home machines (win2k, IIS w/php4 and RH7, apache w/php4).

i've also tried mark's script from above ... here's the thing. change $file in that script to any file/page on the f2s.com servers and you'll get a result.

but if you try to access a file on a server like ... yahoo.com or whatever you get blocked.

i think it's freedom2surf's config of php4 that's perhaps at fault, but haven't been able to confirm this and there's nothing i could see in the phpinfo() to suggest why they're having this problem.
