Hi all,

Sorry for multiple posts. This would be the last one.

Yet another sample code. This cannot be executed on 3v4l.org for security
reasons.

<?php
$sock = fsockopen('www.php.net', '80');
var_dump($sock);

$socks = array($sock);
var_dump(stream_select($socks, $socks, $socks, 1));

//var_dump(stream_select(array($sock), array($sock), array($sock), 1));
//Fatal error: Only variables can be passed by reference in
/home/yohgaki/tmp/ttt.php on line 8
?>
