Hei!
I found another little problem with streams today (in HEAD). The
following script gives a nice assertion error:
<?php
$connection = @stream_socket_client( "tcp://dolly.ez.no:25", $errno, $errstr, 5
);
stream_set_timeout( $connection, 5 );
echo fgets($connection, 512);
echo fgets($connection, 512);
gives:
220 power mailer
