thanks for your reply. i am doing like this using php. but i was getting problem. just run this code. where is the problem please tell me? not getting sessionid. here is the code.

<?
ob_start();
session_start();
  $hostname="http://www.kayak.com";
	$token="mCHpMz2L_a_OrEkz3FSiDg";//"mCHpMz2L_a_OrEkz3FSiDg";
	$sessionid="";
	$searchid="";
	 $searchtype="";
	 $lastcount="";
 class ksearchphpExample
 {
  
	 
	 public function ksearchJavaExample($args){
	 /*print_r($args);
	 echo count($args);exit;*/
		if(count($args) < 4 || count($args) > 5) {
			echo("USAGE:\n".
				"ksearchJavaExample f ORIGIN_AIPORT DESTINATION_AIRPORT DEPART_DATE [RETURN_DATE]\n".
				"ksearchjavaExample h \"city, RC, CC\" CHECKIN_DATE CHECKOUT_DATE\n" );
			exit();
		}
		
		$searchtype='h'; //$args[0].charAt(0);
	
		$sessionid= getsession();
		echo("Session ID:\t".$sessionid );
		
		if($searchtype == 'f' ){
			$searchid= start_flight_search("n", $args[1],$args[2],$args[3],$args[4] );
		}
		
		if( $searchtype == 'h'){
			$searchid= start_hotel_search($args[1],$args[2],$args[3]);
		}
		echo("Search ID:\t".$searchid);
		while (pollResults()) {
			echo("waiting for more...");
		}
	}

 private function getsession(){
		echo("Token:\t\t".$token  );
		$xml = simplexml_load_file($hostname."/k/ident/apisession?token=".$token );

echo $xml->getName() . "<br />";

foreach($xml->children() as $child)
  {
  echo $child->getName() . ": " . $child . "<br />";
  }
		$response=get($hostname+"/k/ident/apisession?token=".$token );
		
	$root=xmlRoot($response);
		$sessionid=$root.getElementsByTagName("sid");
		if( $sessionid.getLength() == 0){
			echo("BAD TOKEN: ".$response);
			exit(1);
		}
		return $sessionid.item(0).getFirstChild().getNodeValue();
	}

 private function fetch($urlstring){
		  $content = "";
	  
		  try {
			$url  = new URL($urlstring);  
	        InputStream is = url.openStream();
	        BufferedReader d = new BufferedReader(new InputStreamReader(is));
	        String s;
	        
	        while (null != (s = d.readLine())) {
	            content = content + s + "\n";
	        }
	        is.close();
	        
		  } catch ( Exception e ) { System.out.println(e.getMessage() ); }
		  return content;
	    }
	
	public static void main(String[] args) {
		ksearchJavaExample ks = new ksearchJavaExample(args);		
	}

 
}
$kps=new ksearchphpExample();
$arg= array ('h','hyderabad,india','03/11/2010','05/11/2010');
echo $kps->ksearchJavaExample($arg);
 
?>

actually code which i get it from the site is in java. so i am changinglike above. this is the java code. how to change this into php.

/*

    javac ksearchJavaExample.java
