php实现图片批量下载到本地实例(可采防盗链)

对于没有防盗链的图片

有防盗链的图片

curlg($url, $fromurl);
    $size = file_put_contents(getcwd() . $filepath . $filename . $ext, $re); //返回大小
    return array(
        $filepath . $filename . $ext,
        $size
    );
}
?>

批量采集代码：

_get("keep"); //1从缓存获取2删除缓存/重新缓存
    $id = $this->_get("id");
    $id = $id ? $id : 0;
    $nextid = $id + 1;
    if ($keep != 1) {
        $data = M(&＃39;Cjlist&＃39;)->where("status=1")->select();
        S("keepcjdata", $data, 3600);
    } else {
        $data = S("keepcjdata");
    }
    $endid = count($data);
    //echo $id;
    //echo $endid;
    if ($endid == $id) {
        exit(&＃39;所有图片下载完成！&＃39;);
    }
    //echo $endid;
    $data2[&＃39;cover_imgurl&＃39;] = $this->imgdown2($data[$id][&＃39;cover_imgurl&＃39;]);
    //echo $data[$id][&＃39;thum_url&＃39;];
    $data2[&＃39;thum_url&＃39;] = $this->imgdown2($data[$id][&＃39;thum_url&＃39;], &＃39;thum_&＃39;); //中型图片type
    $data2[&＃39;id&＃39;] = $data[$id][&＃39;id&＃39;];
    if (!$data2[&＃39;thum_url&＃39;] || !$data2[&＃39;cover_imgurl&＃39;]) {
        $data2[&＃39;status&＃39;] = - 1;
    } else {
        $data2[&＃39;status&＃39;] = 2;
    }
    $res = M(&＃39;Cjlist&＃39;)->save($data2);
    //$this->echosql();
    if ($res) {
        echo &＃39;下载完成ID:&＃39; . $data2[&＃39;id&＃39;] . " 前往下一个ID下载";
    } else {
        echo &＃39;保存出错，正在重试刷新。&＃39;;
    }
    //dump($data2);
    //dump($data);
    
}
?>

同时还可以生成缩略图哦

GrabImage2($picurl, $mulu, time() , $fromurl);
    //$img = file_get_contents($picurl);
    //echo file_put_contents(&＃39;222.jpg&＃39;,$img);
    //exit;
    //$reimg="/20140529/1401333398.jpg";
    //dump($reimg);
    //exit;
    if ($reimg[1] <= 0) {
        exit("下载图片失败");
    }
    $reimg = $reimg[0];
    import(&＃39;ORG.Util.Image&＃39;);
    $Image = new Image();
    $imgurl = getcwd() . $reimg;
    $ext = strrchr($imgurl, ".");
    $thum_name = $Image->thumb($imgurl, "thum_" . time() . $ext, &＃39;&＃39;, &＃39;288&＃39;, &＃39;432&＃39;);
    rename(getcwd() . "/" . $thum_name, getcwd() . $mulu . $thum_name); //移动到文件夹里面
    $imginfo = $Image->getImageInfo(getcwd() . $mulu . $thum_name);
    //dump($imginfo);
    $imgarr[&＃39;cover_url&＃39;] = $reimg;
    $imgarr[&＃39;thum_url&＃39;] = $mulu . $thum_name;
    $imgarr[&＃39;thum_w&＃39;] = $imginfo[&＃39;width&＃39;];
    $imgarr[&＃39;thum_h&＃39;] = $imginfo[&＃39;height&＃39;];
    return $imgarr;
}
?>
