How to fetch search results from another site?

[pankajshr_jpr]

Hi, I am newbie and dont know where to post this topic, sorry if wrong posted.
Actually I want to write a php code which could fetch the flight informations from various airlines sites. These sites have a form in which user can enter information and search the flight. I want to display those results in my site when a user comes to my site and search about flight. For eg. user want to search flights from city-1 to city-2 then he enter the information on my site and my script should search flights according to that information on various airlines sites and display the results with the tag of which ailines is providing this flight.
Could any one please suggest how to do it?

Do any of these sites provide an API? If so, then this should be trivial. Alternatively, you could use cURL to POST/GET to the airline page, scrape the html, parse it and post it on your site. Even better would be if they provided some format such as XML that you could access and parse.

None provides the API nor the XML:(
also frm cUrl i can connect to other server, but How to search the flight on the another website by sending data using GET/POST method and fetch that search result to my site?

Have a look at:
http://us.php.net/curl

Some of the users have contributed comments that show you how to post/get using cURL.

I have looked at it, but they have not posted about how to search the another site by sending query using GET and POST . Could you explain more about search part?

It was on the page, you didn't look hard enough ;) Why reinvent the wheel?

Or more simply:

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post_vars);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1);
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER ,1);
$Rec_Data = curl_exec($ch);
