help with curl

lucilue2003

Hello.. I tried using file_get_contents and that causes 500 internal server error (timeout)...

I figured i'd use curl because it gives me more control.

I am having some difficulty.. I want to use curl and have it retrieve the html file. If that url redirects, I want it to follow the redirectio and then retrieve the html contents..

I am passing this url:

http://click.linksynergy.com/fs-bin/click?id=L5X09timNmo&offerid=45359.10000002&type=4&subid=0

and It does follow the redirection properly.. please advise.
THanks.

function getFile($url){
$ch = curl_init(); // create cURL handle (ch)
if (!$ch)
die("Couldn't initialize a cURL handle");

// set some cURL options
$ret = curl_setopt($ch, CURLOPT_HEADER,        1);
$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
$ret = curl_setopt($ch, CURLOPT_TIMEOUT,        30);

// execute
$ret = curl_exec($ch);

if (empty($ret)) 
{
   // some kind of an error happened
   die(curl_error($ch));
   curl_close($ch); // close cURL handler
} 
else 
{
   $info = curl_getinfo($ch);
   curl_close($ch); // close cURL handler
	   if (empty($info['http_code'])) 
	   {
			die("No HTTP code was returned"); 
	   } 
	   else 
	   {
		echo $ret;
	   }
}

}

i used to use this function in some programs i made. maybe you will find it useful

function curl_get( $getUrl, $referer = "http://www.site.com/default.phtml" )
{
  $ch = curl_init($getUrl);
  curl_setopt($ch, CURLOPT_REFERER, $referer);
  curl_setopt($ch, CURLOPT_USERAGENT, USER_AGENT);
  curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_PATH . "cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_PATH . "cookiejar.txt");
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  $data = curl_exec($ch);
  curl_close($ch);

  return $data;
}

there are a few constants i defined that are used in there, like COOKIE_PATH and USER_AGENT which you will need to change. but the function works, just call it like
$html = curl_get("http://www.site.com/page.php", "http://www.site.com/referrer.php");

I've looked and looked, but I can't see where you give curl the url, as in "curl_init($url);" or "curl_setopt($ch, CURLOPT_URL, $url);".

I'm getting the following on this line:
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Warning: curl_setopt(): You must pass either an object or an array with the CURLOPT_HTTPHEADER, CURLOPT_QUOTE and CURLOPT_POSTQUOTE arguments in /home/mysite/public_html/tags.php on line 67

where did you define $headers ? .. thanks.

sorry, i meant to pull that line out but missed it. i defined headers in a config file, but you should safely be able to remove that line if you want.
