php Laravel 添加自定义类和函数
我现在的情况是这样的.我只有学生的学号,现在我要用列表展示这些学号,姓名,性别,专业等信息.
当然那些信息是存在的,是在我们的基础库中.我要通过我们自己编写的基础库api进行数据的查询操作.
我需要在我的框架中实现一个CurlHelper的类,然后再使用一个方法进行实例化,因为只有部分页面需要用到这些功能.
那么这该怎么在我的框架中实现呢?
首先我在app目录下建立一个文件夹,名为tools,在里面建立两个文件,
一个叫做CurlHelper.php主要有个CurlHelper的类.
另一个是functions.php 这是程序常用的一些函数存放的地方.
类我就不写了,我这里是说明这样一种情况..
函数还是要写一下,因为最后我们需要在控制器或者 模型中进行调用.
function getCurl(){
static $api = null;
if(!$api){
$api = new CurlHelper(//参数);
}
return $api;
}
这就是全部的内容.下面我们需要将CurlHelper类引入框架中.
使用 composer dumpautoload 这时就能够通过依赖注入找到这个类了.
至于常用的这些函数,就是在程序加载时就已经放置到内存中去了.
所以我们甚至可以在public/index.php中通过require app_path().'/tools/functions.php';来加载.
这样,我们就可以在控制器中直接调用我们的getCurl()函数来进行类的实例化了.
Knowledge can change your fate and English can accomplish your future.

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
