I need to write a PHP script to telnet to a router, run a command and fetch the results. does anyone know a telnet connection library in PHP?
Update: This request (as is obvious) was for a long time ago. In the end I had to write the client library that I needed myself. The code for this library (and many more modules) is open source and available on github. Thanks everyone for your answers.
using stdin/stream_select & blocking streams gives you a 20 lines telnet like client
<?
$socket = fsockopen("192.168.52.1", 8000);
if(!$socket)return;
stream_set_blocking($socket, 0);
stream_set_blocking(STDIN, 0);
do {
echo "$ ";
$read = array( $socket, STDIN); $write = NULL; $except = NULL;
if(!is_resource($socket)) return;
$num_changed_streams = @stream_select($read, $write, $except, null);
if(feof($socket)) return ;
if($num_changed_streams === 0) continue;
if (false === $num_changed_streams) {
/* Error handling */
var_dump($read);
echo "Continue\n";
die;
} elseif ($num_changed_streams > 0) {
echo "\r";
$data = fread($socket, 4096);
if($data !== "")
echo "<<< $data";
$data2 = fread(STDIN, 4096);
if($data2 !== "") {
echo ">>> $data2";
fwrite($socket, trim($data2));
}
}
} while(true);
