I am starting to think you may well be right!
I've converted the code to use a TCP socket rather than UDP and it connects (albeit that it then fails because the server is expecting a UDP connection rather than UDP!)....
I'm currently on the hold with the hosting company :/
thanks,

*bump again * - sorry but I'm really stuck with this :(

*bump* still can't work this one out :(

Hi.
May not be the right answer, but it's my understanding of what's written in the manual :)
try changing this line:
[code]$fh = fopen($file, "w+");[/code]
to this:
[code]$fh = fopen($file, "r+");[/code]
I think this may be the cause of your issue because of the definition of "w+" states:
[quote]'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.[/quote]
And the "truncate the file to zero length" bit is likely to be returning you an empty string...
wheras "r+" only has the following definition:
[quote]'r+' Open for reading and writing; place the file pointer at the beginning of the file. [/quote]
Hope it works!
Cheers,

Hi,
Firstly, this is my first post here - so please be gentle :)
OK - I've got a lump of PHP that I am trying to use to communicate with a remote server.
When I run the code my one of my local linux servers (ie, on the same LAN as my desktop pc, but NOT the remote server), the code works perfectly and I get no errors at all.
However, when I upload my code to my webserver, the code fails with the following warning:
[code]Warning: socket_sendto() unable to write to socket [1]: Operation not permitted[/code]
The code is as follows:
[code] $socket=socket_create(AF_INET,SOCK_DGRAM,SOL_UDP);
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array('sec'=>$this->timeout,'usec'=>0));
if (!$socket)
{
return;
}
$packet=null;
$this->packets=null;
if (!socket_sendto($socket,$transmission,strlen($transmission),0x100,$ip,$port))
{
return;
}[/code]
Not sure if it's relevent, but here's the contents of phpinfo from my server and then the webserver:

I have tried googling this and didn't get anything at all (no.. really!)
I also tried searching here a few times, but didn't find anything that I thought was related (but am willing to admit I am wrong!)
If anyone can help, I'd greatly appreciate it!

Socket issue on host server, but not local :(

it'd be nicer if this error message was a little bit more on point, but never-the-less
Thanks again for the answers!
