General purpose function for curl

Hi there,

I was working on a project which included a web scrapper to grab data from a site. For that I had to use curl,  but the problem was the site was checking for cookies on some pages so I have made a function which can serve my application and set cookies when ever required. I have found it on some where and modified to serve my purpose.


/*

*@param: $url  is the URL which will be called

*@param: $params (array)the parameters which will be passed by get method

*@param: $is_coockie_set whether cookies should be set or not

*/

public function curl($url,$params = array(),$is_coockie_set = false)
 {

if(!$is_coockie_set){
 /* create a cookie file */
 $ckfile = tempnam ("/tmp", "CURLCOOKIE");

/*  visit the homepage to set the cookie properly */
 $ch = curl_init ($url);
 curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
 curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
 $output = curl_exec ($ch);
 }

$str = ''; $str_arr= array();
 foreach($params as $key => $value)
 {
 $str_arr[] = "$key=".urlencode($value);
 }
 if(!empty($str_arr))
 $str = '?'.implode('&',$str_arr);
 $ch = curl_init ($url.$str);
 curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile);
 curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);

return  $output = curl_exec ($ch);

}
