The examples in this article share the three delivery methods of PHP session for your reference. The specific content is as follows
Now that you have learned it, take notes and solve the problem of data sharing. Don’t worry about when you will have to manually set and open cookies yourself!
(1) Pass session_id through GET method
<?php $sid = "test"; //设置一个session的id session_id($sid); //将$sid的值当成是session_id,方便做测试 session_start(); //开启session $_SESSION['user'] = "session的传递方式"; ?> <a href="session_3.php?sid=<?php echo session_id(); ?>">test_1.php</a> //将session_id的值用GET传参的方式处理 //php配置文件的修改不同配置项的效果 session.use_only_cookies = //关闭这个选项,就是允许通过get,自动生成session <a href="session_3.php?PHPSESSID=<?php echo session_id(); ?>">test_1.php</a> //这样写,可以省掉自己去通过$_GET去获取值 session.use_trans_sid = 1 //将这个选项打开,将自动的使用session_id <a href="session_2.php">test_2.php</a> //不需要加任何参数, ================================================== <a href="session_3.php<?php echo "?".SID; ?>">test_1.php</a>这个的设置具体哪个有点忘记了反正SID就是一个常量,包含了所需要的内容session信息! //session_3.php页面 session_id($_GET['sid']); //接受sesssion_id; session_start(); var_dump($_SESSION); //打印结果看下
The result is as shown below:
(2) Pass
through hidden values in the form//前面的公共部分不变 //通过form表单中隐藏来传递 <form action="" method="post"> 姓名:<input type="text" name="uname"> <input type="hidden" name="sid" value="<?php echo session_id(); ?>"> <input type="submit" value="确定"> </form> //session_4页面中 $sid = $_POST['sid']; session_id($sid); session_start(); var_dump($_SESSION); //打印结果看下,结果都是一样能实现,就不再重复的输入结果数据
(3) Document format
The above is the entire content of this article. I hope it will be helpful for everyone to learn and understand the delivery method of PHP session.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),
