php multi curl problem

i want to get several pages thru curl_exec, first page is come normally, but all others - 302 header, what reason?

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, ROOT_URL);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec($curl); // here good content
curl_close($curl);

preg_match_all('/href="(\/users\/[^"]+)"[^>]+>\s*/i', $content, $p);

for ($j=0; $j<count($p[1]); $j++){
    $new_curl = curl_init();
    curl_setopt($new_curl, CURLOPT_URL, NEW_URL.$p[1][$j]);
    curl_set开发者_开发知识库opt($new_curl, CURLOPT_RETURNTRANSFER, 0);
    $content = curl_exec($new_curl); // here 302    
    curl_close($new_curl);

preg_match('/[^@]+@[^"]+/i', $content, $p2);

}

smth like this

You probably want to provide a sample of your code so we can see if you're omitting something.

302 response code typically indicates that the server is redirecting you to a different location (found in the Location response header). Depending on what flags you use, CURL can either retrieve that automatically or you can watch for the 302 response and retrieve it yourself.

Here is how you would get CURL to follow the redirects (where $ch is the handle to your curl connection):

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects 

You can use curl multi which is faster and can get data from all the url's in parallel. You can use it like this

//Initialize
$curlOptions = array(CURLOPT_RETURNTRANSFER => 1);//Add whatever u additionally want.
$curlHandl1 = curl_init($url1);
curl_setopt_array($curlHandl1, $curlOptions);

$curlHandl2 = curl_init($url2);
curl_setopt_array($curlHandl2, $curlOptions);

$multi = curl_multi_init();
curl_multi_add_handle($multi, $curlHandle1);
curl_multi_add_handle($multi, $curlHandle2);

//Run Handles
$running = null;
do {
  $status = curl_multi_exec($mh, $running);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($running && $status == CURLM_OK) {
  if (curl_multi_select($mh) != -1) {
    do {
      $status = curl_multi_exec($mh, $running);
    } while ($status == CURLM_CALL_MULTI_PERFORM);
  }
}

//Retrieve Results
$response1 = curl_multi_getcontent($curlHandle1);
$status1 = curl_getinfo($curlHandle1);

$response1 = curl_multi_getcontent($curlHandle1);
$status1 = curl_getinfo($curlHandle1);
