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.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
