How to find out which url failed to execute in curl_multi_exec?

Question

I wrote a class to make it easier to use multi cURL queries. I want to log errors when I get a 404 error or any other error. I already have CURLOPT_FAILONERROR true.

I am currently using curl_multi_info_read() .

and this is my code:

 $active = null; do { $multi_exec = curl_multi_exec($this->_multi_handle, $active); } while ($multi_exec == CURLM_CALL_MULTI_PERFORM); while ($active && $multi_exec == CURLM_OK) { if (curl_multi_select($this->_multi_handle) != -1) { do { $multi_exec = curl_multi_exec($this->_multi_handle, $active); $info = curl_multi_info_read($this->_multi_handle); if ( $info['result'] != 0 ) { $this->_errors[] = $info; // currently storing the whole array } } while ($multi_exec == CURLM_CALL_MULTI_PERFORM); } } 

The error result is an array like this:

 Array ( [0] => Array ( [msg] => 1 [result] => 22 // on success this is 0 [handle] => Resource id #4 // does this help in finding the url if I have the handle ID ? ) 

So how can I get the url where the error occurred? this gives me the descriptor resource id

and thanks in advance.

Depending on what you really need, you can pass this handle to curl_error or curl_errno to check for errors, and you can use curl_getinfo to extract the URL from this handle:

 curl_getinfo($info['handle'], CURLINFO_EFFECTIVE_URL);
