Multiple Socket Read and Writes?

Hello all, I am having a problem with getting multiple socket reads working in a simple socket server! The writes appear to be working but the reads seam to only allow one read? I know i am missing something. Could even be my approach is totally wrong Currently I have:

          $input = socket_read($client[$i]['sock'] , 2024,PHP_BINARY_READ );
          if ($input == null) {
                // Zero length string meaning disconnected
                echo "null input 1\n";
                unset($client[$i]);
          }
          elseif ($input == 'exit') {
                // requested disconnect
                echo "exit\n";
                socket_shutdown($client[$i]['sock']);
                socket_close($client[$i]['sock']);
          }
        elseif ($input=="kill") {
                echo "kill\n";
                socket_shutdown($sock);
                socket_close($sock);
                die;
        }
        elseif ($input) {
                // strip white spaces and write back to user
                echo " <-- ". $input."\n";
                socket_write( $client[$i]['sock'],dechex(50) );
                echo " --> SYN  ".socket_strerror(socket_last_error())."\n";
                socket_write( $client[$i]['sock'],dechex(50) );
                echo " --> SYN  ".socket_strerror(socket_last_error())."\n";
                socket_write( $client[$i]['sock'],dechex(50) );
                echo " --> SYN  ".socket_strerror(socket_last_error())."\n";
                //$output = ereg_replace("[ \t\n\r]","",$input).chr(0);
                if ( false == ( socket_write( $client[$i]['sock'],dechex(46) ) ) ) {
                        echo "socket_write() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
                }
                else {
                        echo " --> ENQ  ".socket_strerror(socket_last_error())."\n";
                            $input1 = socket_read($client[$i]['sock'] , 2024,PHP_BINARY_READ );
                        echo "<-- ". $input1."  " . socket_strerror(socket_last_error()) ."\n";
                };
        }
        else {
                echo "nothing on INPUT\n";
        }
