Question

我想遍历多个文件上传并将其添加到我的json

这是我目前一次上传的内容：

$file_prefix = md5_file($tmp_file);
$file_name = $file_prefix . "_" . rand(1000, 99999) . "_{$session_check_data['id']}".".jpg";
$target_file = $vehicle_image_folder . "/".$file_name;

list($width, $height, $type, $attr) = getimagesize($tmp_file);


$image = new \Gumlet\ImageResize($tmp_file);

 if($width > 1200) {
        $image->resizeToWidth(1200);
 }

$image->save($target_file, IMAGETYPE_JPEG);

if ($this->request->get('upload_thumb')) {
    $thumbnail_file = $vehicle_image_folder . "/thumb_".$file_name;
    $this->app['monolog']->info("thumbs required");
    $image = new \Gumlet\ImageResize($target_file);
    $image->resizeToWidth(400);
    $image->save($thumbnail_file, IMAGETYPE_JPEG);
}

这是我试图做的事情

$files = array();
$l = 3;
foreach ($tmp_file as $k => $l) {
    $file_prefix = md5_file($k);
    foreach ($l as $i => $v) {
        if (!array_key_exists($i, $files))
            $files[$i] = array();
        $files[$i][$k] = $v;
    }
}
$counter = 1;


foreach ($files as $file) {
    $count = $counter++;

    $file_name = $file_prefix . "_" . rand(1000, 99999) . "_{$session_check_data['id']}".".jpg";
    $target_file = $vehicle_image_folder . "/".$file_name;
    list($width, $height, $type, $attr) = getimagesize($file);

    $image = new \Gumlet\ImageResize($file);

    if ($width > 1200) {
        $image->resizeToWidth(1200);
    }

    $image->save($target_file, IMAGETYPE_JPEG);

    if ($this->request->get('upload_thumb')) {
        $thumbnail_file = $vehicle_image_folder . "/thumb_" . $file_name;
        $this->app['monolog']->info("thumbs required");
        $image = new \Gumlet\ImageResize($target_file);
        $image->resizeToWidth(400);
        $image->save($thumbnail_file, IMAGETYPE_JPEG);
    }
}

然后我想在loc中的JSON中返回3个图像，也许是loc1，loc2，loc3？：


return $this->app->json(['success' => 1, 'info' => 'uploaded', 'loc' => $file_name]);

我希望能够显示已上传的3张图片

如何循环上传多个文件，然后添加到json数组中？
