$result = file_get_contents("www.example.com?param1=value1&param2=value2");

But some times GET does not work, specially when you need to communicate with other platforms "other servers" which already written and expect a POST request.

PHP script to find a PC location in a network based on its MAC address

NOTE: Some regular expressions may be not accurate in all circumstances, take it as is at your risk, or feel free to change it. <?php function login($telnet,$username,$password) { $response = readBuffer($telnet); if($username != null) fputs($telnet,"{$username}\r\n"); fputs($telnet,"{$password}\r\n"); $response .= readBuffer($telnet); // if the switch in user mode // then go to exec mode if(preg_match("/[a-z0-9_\(\)\-]+>$/i",$response) ) { $response .= sendCommand($telnet,"en"); $response .= sendCommand($telnet,$password); } preg_match("/[a-z0-9_\(\)\-]+[#>]$/i",$response,$out); return str_replace("#","",$out[0]); // return hostn
