I am getting problem while using fwrite in php. the following code works in my local computer but gives error in server.
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if(!$fp) {
echo 'Error: '.$errno.', '.$errstr;
} else {
fwrite($fp, 'kool');
}
There is no error with fsockopen. it passes and gives no error. fwrite is not being able to write. it fails and returns no error only false
This is a permissions issue with the Apache/Nobody user accessing a remote file that it doesn't have permission to modify/read/write/execute.
You should also print the error message(s) for debugging
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if(!$fp) {
echo "Error No: ".$errno."<br />\n";
echo "Error Str: ".$errstr."<br />\n";
} else {
fwrite($fp, 'kool');
}
If you're on a shared host, most likely your server does not allow outbound connections on port 80. Usually only inbound connections are allowed.
