another question for the continuing saga ..
I am trying to undertake a handshake with the telnet (tn3270) server ..
using
$get=socket_read($socket, 128, PHP_BINARY_READ );
i now need to step through $get byte by byte
how do i do an equivilent fgetc? ie
while (!feof($get)) {
echo fgetc($iget);
}
but with the socket???
entire code below. ...
cheers
