socket read byte by byte

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($iget); } but with the socket??? entire code below. ... cheers brendan ----------------------- <?php ################ SET BINARY CODES ############################# function makeChr($loud="off"){ for ($i = 0; $i < 256; ++$i) { static $genNum; $genNum++; $bin_array[$genNum]=(chr($genNum));

     if ($loud=="on") {
         echo "chr($genNum) will output '";
         echo (chr($genNum));
         echo "'<br> \n";
