i want to do a website wich is having search functionality. in this i have to do search flights,hotels etc.., some one suggested me to use kayak api for this. i searched every thing for this. but i didn't get any idea. anyone could suggest me how to use this api in my site.
thanks.
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.

?>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.
