Arancaytar Posted September 27, 2006 Share Posted September 27, 2006 I can't figure out what I'm doing wrong here. The code block is intended to take the URL contained in $url, send a HEAD request and then print the header that comes back.For this test, I set $url="http://www.google.com/".[code=php:0]$url="http://www.google.com/";$ch = curl_init();$timeout = 5;curl_setopt ($ch, CURLOPT_URL, $url);curl_setopt( $ch, CURLOPT_CUSTOMREQUEST,"HEAD");curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$head=curl_exec($ch);var_dump($head);curl_close($ch);[/code][url=http://php.net/manual/en/function.curl-exec.php]curl_exec[/url] only returns true - even though it should return the entire response since I set RETURNTRANSFER to 1.Any ideas?

shoz Posted September 27, 2006 Share Posted September 27, 2006 You can use CURLOPT_NOBODY option to send a HEAD request and CURLOPT_HEADER to retrieve the headers in the output. [url=http://www.php.net/curl_setopt]curl_setopt()[/url][code]$ch = curl_init();$url = 'http://www.google.com/';curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, 1);curl_setopt($ch, CURLOPT_NOBODY, 1);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$r = curl_exec($ch);$headers = explode("\r\n\r\n", $r);$header = $headers[(count($headers) - 2)];print $header;[/code]I've noticed that in cases where there are redirects(note the CURLOPT_FOLLOWLOCATION), the header output includes all the previous headers as well. Which is why I've included the explode and $headers[(count...)] to retrieve the last header returned. Quote Link to comment Share on other sites More sharing options...
Arancaytar Posted September 27, 2006 Author Share Posted September 27, 2006 Thanks a lot!I still don't understand why the CUSTOMREQUEST thing doesn't seem to work, but I got headers with your method, and that's what counts.One thing though: Will this fetch the whole page, thus increasing the amount of data actually transferred? At the volume I will be using it, this won't be a real problem, but still. Edit: Okay, NOBODY will prevent the whole page from being fetched. So it appears to act exactly the same as a HEAD request.Now I'm only wondering why you can't use customrequest for this... Quote Link to comment Share on other sites More sharing options...
