上传操作代码

 代码如下

   
   


 
    if($_FILES["myfile"]["error"] > 0) {      //判断文件是否可以成功上传到服务器，0表示上传成功
        echo "Error: ";
 
        switch ( $_FILES["myfile"]["error"]  ) {
            case UPLOAD_ERR_OK:
                $response = "There is no error, the file uploaded with success.";
                break;
            case UPLOAD_ERR_INI_SIZE:
                $response = "The uploaded file exceeds the upload_max_filesize directive in php.ini.";
                break;
            case UPLOAD_ERR_FORM_SIZE:
                $response = "The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.";
                break;
            case UPLOAD_ERR_PARTIAL:
                $response = "The uploaded file was only partially uploaded.";
                break;
            case UPLOAD_ERR_NO_FILE:
                $response = "No file was uploaded.";
                break;
            case UPLOAD_ERR_NO_TMP_DIR:
                $response = "Missing a temporary folder. Introduced in PHP 4.3.10 and PHP 5.0.3.";
                break;
            case UPLOAD_ERR_CANT_WRITE:
                $response = "Failed to write file to disk. Introduced in PHP 5.1.0.";
                break;
            case UPLOAD_ERR_EXTENSION:
                $response = "File upload stopped by extension. Introduced in PHP 5.2.0.";
                break;
            default:
                $response = "Unknown error";
                break;
        }
        echo $response;
         
         
        exit;       //如果$_FILES["myfile"]["error"]大于0都是有错误，输出错误信息并退出程序
    }
     
     //获取上传文件的MIME类型中的主类型和子类型
    list($maintype,$subtype)=explode("/",$_FILES["myfile"]["type"]);    
     
    if ($maintype=="text") {    //通过主类型限制不能上传文本文件，例如.txt .html .php等文件文件
     
        echo "问题: 不能上传文本文件。";
        exit;                //如果用户上传文本文件则退出程序
         
    }
 
    $upfile = "./uploads/".time().$_FILES["myfile"]["name"];     //定义上传后的位置和新文件名
     
    if ( is_uploaded_file($_FILES["myfile"]["tmp_name"]) ) {     //判断是否为上传文件
     
        if ( !move_uploaded_file($_FILES["myfile"]["tmp_name"], $upfile) ) {   //从移动文件
            echo "问题: 不能将文件移动到指定目录。";
            exit;
        }
         
    }else{
         
        echo "问题: 上传文件不是一个合法文件: ";
        echo $_FILES["myfile"]["name"];
        exit;
         
    }
 
    echo "文件 :  ".$upfile."  上传成功, 大小为 : " .$_FILES["myfile"]["size"]."！
";   //如果文件上传成功则输出
