php知识：php怎么使用multiple属性实现多文件上传及信息解析？（图文+视频）

    
    



 选择文件进行上传： 

    

var_dump($_FILES);

 $v) {
                $files[$i]['name'] = $file['name'][$k];
                $files[$i]['type'] = $file['type'][$k];
                $files[$i]['tmp_name'] = $file['tmp_name'][$k];
                $files[$i]['error'] = $file['error'][$k];
                $files[$i]['size'] = $file['size'][$k];
                $i++;
            }
        }
    }
    return $files;
}

/**
 * 文件上传
 * @param $fileInfo
 * @param string $upload
 * @param array $imagesExt
 * @return string
 */
function upload_file($fileInfo, $upload = "./upload", $imagesExt = ['gif', 'png', 'jpg'])
{
    $res = [];
    if ($fileInfo['error'] === 0) {
        $ext = strtolower(pathinfo($fileInfo['name'], PATHINFO_EXTENSION));
        if (!in_array($ext, $imagesExt)) {
            $res['mes'] = "文件非法类型";
        }
        if (!is_dir($upload)) {
            mkdir($upload, 0777, true);
        }
        if ($res) {
            return $res;
        }
        $fileName = md5(uniqid(microtime(true), true)) . "." . $ext;
        $destName = $upload . "/" . $fileName;
        if (!move_uploaded_file($fileInfo['tmp_name'], $destName)) {
            $res['mes'] = "文件上传失败！";
        }
        $res['mes'] = $fileInfo['name'] . "文件上传成功！";
        $res['dest'] = $destName;
        return $res;
    } else {
        switch ($fileInfo['error']) {
            case 1:
                $res['mes'] = '上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值';
                break;
            case 2:
                $res['mes'] = '上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值';
                break;
            case 3:
                $res['mes'] = '文件只有部分被上传';
                break;
            case 4:
                $res['mes'] = '没有文件被上传';
                break;
            case 6:
                $res['mes'] = '找不到临时文件夹';
                break;
            case 7:
                $res['mes'] = '文件写入失败';
                break;
        }
        return $res;
    }
}

$files = getFile();

foreach ($files as $fileInfo) {
    $res = upload_file($fileInfo);
    echo $res['mes'];
    var_dump($res['dest']);
}
