PHP: curl_multi_getcontent - Manual

If CURLOPT_RETURNTRANSFER is an option that is set for a specific handle, then this function will return the content of that cURL handle in the form of a string. michael at xendica dot com ¶

     This seems to work as expected for me - allowing me to get the content from a curl_multi operation into variables :
     

     

     (Thanks go to many other notes in related documentation (there is much copy/pasting) all I did was add the relevant line(s))
     

     

     <?
     

     $aURLs = array("
     
      http://www.php.net
     
     ","
     
      http://www.w3cschools.com
     
     "); // array of URLs
     

     $mh = curl_multi_init(); // init the curl Multi
     

     

     $aCurlHandles = array(); // create an array for the individual curl handles
     

     

     foreach ($aURLs as $id=>$url) { //add the handles for each url
     

     $ch = curl_setup($url,$socks5_proxy,$usernamepass);
     

     $ch = curl_init(); // init curl, and then setup your options
     

     curl_setopt($ch, CURLOPT_URL, $url);
     

     curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // returns the result - very important
     

     curl_setopt($ch, CURLOPT_HEADER, 0); // no headers in the output
     

     

     $aCurlHandles[$url] = $ch;
     

     curl_multi_add_handle($mh,$ch);
     

     }
     

     

     $active = null;
     

     //execute the handles
     

     do {
     

     $mrc = curl_multi_exec($mh, $active);
     

     }
     

     while ($mrc == CURLM_CALL_MULTI_PERFORM);
     

     

     while ($active && $mrc == CURLM_OK) {
     

     if (curl_multi_select($mh) != -1) {
     

     do {
     

     $mrc = curl_multi_exec($mh, $active);
     

     } while ($mrc == CURLM_CALL_MULTI_PERFORM);
     

     }
     

     }
     

     

     /* This is the relevant bit */
     

     // iterate through the handles and get your content
     

     foreach ($aCurlHandles as $url=>$ch) {
     

     $html = curl_multi_getcontent($ch); // get the content
     

     // do what you want with the HTML
     

     curl_multi_remove_handle($mh, $ch); // remove the handle (assuming  you are done with it);
     

     }
     

     /* End of the relevant bit */
     

     

     curl_multi_close($mh); // close the curl multi handler
     

     

     ?>

     You can use curl_multi_getcontent() on a curl handle that was executed with curl_exec() (and not added to a multi handle).
     

     However, this is not very useful because curl_multi_getcontent() will return the same as curl_exec() then.
     

     

     
      <?php
      

      $ch
     
     
      =
     
     
      curl_init
     
     
      (
     
     
      '
      
       http://www.example.com/
      
      '
     
     
      );
      

     
     
      curl_setopt
     
     
      (
     
     
      $ch
     
     
      ,
     
     
      CURLOPT_RETURNTRANSFER
     
     
      ,
     
     
      1
     
     
      );
      

     
     
      $a
     
     
      =
     
     
      curl_exec
     
     
      (
     
     
      $ch
     
     
      );
      

     
     
      $b
     
     
      =
     
     
      curl_multi_getcontent
     
     
      (
     
     
      $ch
     
     
      );
      

     
     
      var_dump
     
     
      (
     
     
      $a
     
     
      ===
     
     
      $b
     
     
      );
      

     
     
      curl_close
     
     
      (
     
     
      $ch
     
     
      );
      

     
     
      ?>
      

     
     will return:
     

     

     bool(true)
