namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
public function upImg(){
$dir = "./upload/";
if (!is_dir($dir)){
mkdir($dir, 0777);
};
foreach ($_FILES["img"]["name"] as $key => $tempName){
$imgname = $_FILES["img"]["name"][$key];
$tmp = $_FILES['img']['tmp_name'][$key];
move_uploaded_file($tmp, $dir . $imgname );
$data['url'][]=array(
'url'=>$dir.$imgname ,
);
}
var_dump(json_encode($data['url']));exit();
