How vk behaves when parsing, the essence is that you need to select all users from the group simply by links to their aki, and worked on the api to pull articles from the group, but here is the case when not the creator of the group wants to do this.
UPD implemented the function of selecting groups and meeting in a txt file of all users. The code is not very good, don't shout, but it works

<?php
error_reporting(0);
$handle = fopen("file.txt", "w");


if(filter_has_var(INPUT_POST, 'tarea')){
    $_POST['tarea'] = explode("\n", $_POST['tarea']);


    for ($i=0; $i < count($_POST['tarea']) ; $i++) {
        if(!$_POST['tarea'][$i] == ""){
            $club = strrpos($_POST['tarea'][$i],"m/club");
            if( $club !== false){
                $res[] = substr($_POST['tarea'][$i],$club+6);
            } else {
                $pos = strrpos($_POST['tarea'][$i],"m/")+2;
                $res[] = substr($_POST['tarea'][$i],$pos);
            }


        }

    }


    function getSslPage($url) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_REFERER, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        $result = curl_exec($ch);
        curl_close($ch);
        return $result;
    }

    function check($value, $handle) {
        fwrite($handle, "--------------------------------- ");
        $id_group = trim($value);
        $url = "http://api.vkontakte.ru/method/groups.getMembers?group_id={$id_group}&count=0&offset=0";
        $wall = json_decode(getSslPage($url),true);
        fwrite($handle, "$id_group\n");
            $count = $wall['response']['count'];
        fwrite($handle, " $count\n ");
            if($count > 1000) {

                foreach (range(0,$count, 50 ) as $number) {

                    $offset = "&offset=".$number;
                    $url = checkUrl($url = "http://api.vkontakte.ru/method/groups.getMembers?group_id={$id_group}&count=50&offset=0", $offset);
                    $wall = json_decode(getSslPage($url),true);


                    foreach ($wall['response']['users'] as $vk_ac) {


                        fwrite($handle, "{$vk_ac}\n");
                    }

                }
            }

    }

    function checkUrl($url, $offset){
        $pos = strrpos($url,"&offset=");
        $newurl = substr_replace($url,$offset,$pos);
        return $newurl;
    }

    foreach ($res as $value) {

        check($value,$handle);
    }

    fclose($handle);
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename('file.txt'));
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize('file.txt'));
    readfile('file.txt');
    exit;
}
