I have been banging my head against a wall all day trying to work
this problem out. To recap my earlier post, I have a simple socket
listener that handles the incoming string fine with socket_read and
then it fires off the application as it should. When it returns the
data to the socket only the first 1024 bytes get sent.
I have done some testing and for the life of me I can not find a way
to loop through the buffer. Everything I try still results in only
the first 1024 bytes.

Does anyone have any clues?
You've already been given a clue... read the manual:
http://php.net/socket_write
I know you said you read it, but you obviously haven't. To quote...
"Returns the number of bytes successfully written to the socket or
*FALSE* on error"
You are not even checking the return value from socket_write for an
error, nevermind to see the number of bytes actually sent. The
socket_write function, like many other similar functions, is not
guaranteed to send exactly what you give it, even if you provide the
third parameter.
Your code for sending data should be structured something like the
following *untested* code...
$len = strlen($datatosend);
$offset = strlen($datatosend);
while ($offset < $len)
{
$sent = socket_write($client, substr($datatosend, $offset), $len -
$offset);
if ($sent === false)
{
// An error occurred, break out of the while loop
break;
}
$offset += $sent;
}
if ($offset < $len)
{
// An error occurred, use *socket_last_error()*
<http://uk2.php.net/manual/en/function.socket-last-error.php>* and
**socket_strerror()*
<http://uk2.php.net/manual/en/function.socket-strerror.php> to find out
what happened
}
else
{
// Data sent ok
}
Your problem is that you made lazy assumptions, and we all know that
assumptions are the mother of all fsckups. Now please irradiate your
hands and try again.
