上传操作代码

    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
?>
