socket_write buffer problem

[Richard Luckhurst <rluckhurst@xxxxxxxxxxxxx>]

Hi List

I am working with an application that has to run as a socket listener. It
receives a string from another application on a certain socket and then does
some processing and then passes the result back to the client application via
the socket. Here is the listener code I am using

while(true)
        {
                $client = socket_accept($socket);
                
                $arev_data = socket_read($client, 1024);
                
                $yresponse = build_XML_request($arev_data);
                
                socket_write($client, $yresponse);
                
                socket_close($client);
                
        }
        socket_close($socket);

The application is working fine but I have just noticed that when the $yresponse
variable is larger than 1024 bytes the string returned to the client is
truncated. I just had a look at the php manual for socket_write and it
mentions that truncating the data at the buffer size can be a problem. The
manual does not offer any possible solutions though. I am stumped here as the
value for $yresponse will often be larger than 1024 bytes and its length is
quite variable.

Does anyone have any suggestions on how I can make sure the entire contents of
$yresponse are passed back to the client?
