I've setup a simple stream_socket_client and socket server scripts. If I run the server script on a different machine than the client and send data, not all the data reaches the server. If I run the server and client on the same machine there is no problem. If I play around with the size of the chunks I'm sending I get slightly different results, but it never resolves the problem entirely.
I'd normally consider this a network issue, but I've seen this work on a PHP 4.3.x box as the client and a server somewhere else on the Internet.
Are there factors that impact how much data stream_socket_client can send? I've checked my php.ini's to make sure there is plenty of memory available and timeouts aren't too short.
Any thoughts? Thanks
Client:
#!/usr/bin/php -q
<?php
$fp = stream_socket_client("xxx.xxx.xxx.xxx:6016", $errno, $errstr, 30);
if ($fp)
{
$xml = file_get_contents('/data/bin/the.xml');
stream_set_blocking($fp, false);
$parts = str_split($xml, 128);
foreach ($parts as $chunk)
{
fwrite($fp, $chunk);
}
$result = fwrite($fp, "\r\n");
fclose($fp);
}
Server:
#!/usr/bin/php -q
<?php
error_reporting(E_ALL);
/* Allow the script to hang around waiting for connections. */
set_time_limit(0);
/* Turn on implicit output flushing so we see what we're getting
* as it comes in. */
