Read from socket until no more data

[aximbigfan]

Hi,

I am having a problem with socket_read(). Socket_read wants a secound parm to tell it how much data to read. The problem is that there is no fixed amount. I want it to read as much as there is to read. I have tried putting 0 and not including that parm, it just complains and fails.

Is there any way I can just read until there is no more data?

Thanks,
Chris

use $buffer as the string you want to store the info to, first note explains most of it.

Thanks Scragar... For some reason you are always the first one to solve my stuff...

Erm... How does the syntax go?

I have this: $message = socket_recv($spawn, $message);
but get this:
Warning: socket_recv() expects exactly 4 parameters, 2 given in /opt/SocketServer.php on line 125


If I supply a len, isn't it just going to chop like the other function?

Thanks,
Chris

$fullResult = '';
while(false !== socket_recv($spawn, $message, 1024,0)){
  if($message != null)
    $fullResult .= $message;
};
echo $fullResult; 

EDITED: removed a few characters from the second line that throw an error

Ok, I see...

Thanks a bunch!

Hi Scragar, sorry to bother you again,

This part is failing. It just hangs.

//Read sent data and report
    echo "Reading message...         ";
    $message = "";
        while (false !== socket_recv($spawn, $part_message, 1024, 0))
        {
        if ($part_message != NULL)
            $message .= $part_message;
        }
        
    if (!$message)
        echo "Error!\n";
    else
        echo "OK\n";

try this and let me know the result

$len = socket_recv($spawn, $part_message, 1024, MSG_TRUNC);
echo $len; 

I'm sorry that it's not much, but I'm curious to see how the length is altered by that flag(since it's completely undocumented), and I don't have the tools to test it myself for a little while(not on any of my machines and I don't think my neighbour will like me installing strange stuff on her's when I'm supposed to be fixing it).

I get this:
Warning: socket_recv() expects parameter 4 to be long, string given in /opt/SocketServer.php on line 125

when that flag is set to 4 it runs, but does NOT ignore the transfer limit.

HOWEVER:::

    $message = socket_recv($spawn, $part_message, 1024, 0);
    $message = $part_message; 

Seems to collect data... edit: but it does not ignore the limit.
