    一。 APC模块的安装与配置

    我的环境是Windows,需要去下载php_apc. dll文件,并把php_apc.dll放到php/ext中,并在php.ini中添加以下语句:

    extension = php_apc.dll

    apc.rfc1867 = 1

    apc.max_file_size = 200M

    另外,由于需要上传大文件,所以,在php.ini中,以下选项也需要更改:

    upload_max_filesize = 1000M

    post_max_size = 1000M

    max_execution_time = 600 ;每个PHP页面运行的最大时间值(秒),默认30秒

    max_input_time = 600 ;每个PHP页面接收数据所需的最大时间,默认60秒

    memory_limit = 128M ;每个PHP页面所吃掉的最大内存,默认8M

    二。 获取进度条代码

    getprogress.php

   

    session_start();

    if(isset($_GET['progress_key'])) {

    $status = apc_fetch(‘upload_'.$_GET['progress_key']);

    if($status['total']!=0 && !emptyempty($status['total'])) {

    echo json_encode($status);

    }

    else {

    echo (0);

    }

    }

    ?>

   

    session_start();

    if(isset($_GET['progress_key'])) {

    $status = apc_fetch('upload_'.$_GET['progress_key']);

    if($status['total']!=0 && !empty($status['total'])) {

    echo json_encode($status);

    }

    else {

    echo (0);

    }

    }

    ?>

    这里用到了json,传数据非常方便。

    $status对象是拥有以下字段的数组:

    total: 文件总大小

    current: 到目前为止收到的文件数

    rate: 上传速度(以字节/秒为单位),不过要在上传完成之后才能有。

    filename: 文件名

    name: 变量名

    temp_filename: PHP 保存文件的临时副本的位置

    cancel_upload: 上传已取消(1),还是未取消(0)

    done: 上传已完成(1),还是尚未完成(0)

    这里,我们用json全部传到页面,方便后面利用。

    三。 主文件

    upload.php

   

    $id = md5(uniqid(rand(), true));

    ?>

   

   

   

Upload Example

   

   

   

   

    action=“target.php” method=“POST”>

   

    id=“progress_key” value=“” />

   

   

    type=“submit” value=“Upload!” />

   

   

    “width: 500px; height: 20px; border: 1px solid black; display:none;”>

   

    “position: relative; height: 20px; background-color: gray; width: 0%; ”>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
