I want to get last modification time of the remote file. I am using this code I found here on stackoverflow
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,$url);
//don't fetch the actual page, you only want headers
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_HEADER, true);
//stop it from outputting stuff to stdout
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
// attempt to retrieve the modification date
curl_setopt($curl, CURLOPT_FILETIME, true);
$result = curl_exec($curl);
echo $result;
$info = curl_getinfo($curl);
print_r($info);
if ($info['filetime'] != -1) { //otherwise unknown
echo date("Y-m-d H:i:s", $info['filetime']); //etc
}
Problem with this code I am getting filetime = -1 all the time. But when I delete
curl_setopt($curl, CURLOPT_NOBODY, true);
then I am getting correct modification time.
Is it possible to get last modification time but with
curl_setopt($curl, CURLOPT_NOBODY, true);
included in the script. I just need header of the page, not body.
Thanks in advance
The filemtime() function returns the last time the file content was modified.
Windows file properties You can also see the modified date by viewing the file properties. Right-click the file and select Properties. In the Properties window, the Created date, Modified date, and Accessed date is displayed, similar to the example below.
Using getlastmod() Function: The getlastmod() function is used to get the last modification time of the current page.
Given the added information in our Q/A discussion, it sure sounds like you're just not getting a response. It could be that the server is configured with some sort of which intentionally or inadvertently blocks HEAD requests for some reason, or there could be a difficult proxy involved.
When I'm debugging PHP cURL stuff, I often find it useful to use a *nix box (my mac, or ssh to a server) and run the requests from the command line, so I can see the result without worrying about if the PHP is doing the right thing, until I get the cURL part working. For instance:
$ curl --head stackoverflow.com
HTTP/1.1 200 OK
Cache-Control: public, max-age=49
Content-Length: 190214
