$page = "/index.htm";
$fp = fsockopen( "$host", 80, $errno, $errdesc );
if ( ! $fp ) {
die ( "Couldn't connect to $host:\nError: $errno\nDesc: $errdesc\n" );
}
$request = "GET $page HTTP/1.0\r\n";
$request .= "Host: $host\r\n";
$request .= "Referer: http://www.manongjc.com/page.html\r\n";
$request .= "User-Agent: PHP test client\r\n\r\n";
$page = array();
fputs ( $fp, $request );
while ( ! feof( $fp ) ) {
$page[] = fgets( $fp, 1024 );
}
fclose( $fp );
print "the server returned ".(count($page))." lines!";
?>
