[SOLVED] fread

[unidox]

I have this script:

 

$url = "http://www.site.com/license.php?key=" . SITE_LIC . "&ref=" . $_SERVER["SERVER_NAME"] . "";
$lic = @fopen($url, "r+");
$lic = @fread($lic, 8192);

if ($lic == "0") {
header("Location: http://www.site.com/index.php?p=lic_invalid&site=" . $_SERVER["SERVER_NAME"] . "");
exit();
}

fclose($lic);

 

If I type the url in my address bar, it outputs 1 as desired. But when I try to echo $lic, nothing even outputs. Whats wrong?

You are having some errors somewhere. Take away the '@' sign, as this suppresses errors and just skips over them. This may tell you what your problem is.

 

Using the '@' sign is almost always sloppy programming, and should only ever be used a very small number of situations.

I don't know of any situation where it is needed, that is what if/else is for.

I found one when working with gd image functions a while back. I can't remember the exact details, but it returned an error when nothing was found, instead of a -1 or something that I could have used. In that one situation it was preferable to use the '@' symbol, but I have never found any other situations.
