Reproduce code: --------------- <?php function fetchData($URLs) { // set empty lists $errors = array(); $cache = array(); //create the multiple cURL handle $mh = curl_multi_init(); foreach($URLs as $i=>$URL) { // initialize a cURL session $sessions[$i] = curl_init(); // set URL and other appropriate options curl_setopt($sessions[$i], CURLOPT_URL, $URL); curl_setopt($sessions[$i], CURLOPT_HEADER, 0); curl_setopt($sessions[$i], CURLOPT_RETURNTRANSFER, 1); //add handles curl_multi_add_handle($mh, $sessions[$i]); } //execute the handles do { curl_multi_exec($mh, $running); } while ($running > 0); foreach($sessions as $i=>$session) { // get file content if (curl_multi_getcontent($session) == false) { $errors[$i] = curl_error($session); } // remove handle curl_multi_remove_handle($mh, $sessions[$i]); } // close multi handle curl_multi_close($mh); return $errors; } /*--- CASE 'A' ---*/ // valid URLs $URLsA[] = 'http://www.google.com/'; $URLsA[] = 'http://www.yahoo.com/'; // Invalid URL. This site does not exist. This should produce an error message. $URLsA[] = 'http://www.mysite-abc123.com/'; $errorsA = fetchData($URLsA); print_r($errorsA); /*--- CASE 'B' ---*/ // valid URL $URLsB[] = 'http://www.google.com/'; // Invalid URL.
