Laravel 5 Framework Learning: Getting Started with Laravel and New Projects, Laravel New Projects
This series of articles is the notes of the introductory series of videos in laracasts.com. I have made some modifications. You can refer to this series of articles to learn Laravel 5. The author of the original video is Jeffrey Way, thank you. The system I use is a Mac system, but regardless of Mac or Windows users, it is recommended to use a virtual machine to install Linux (the server version is enough), and then develop using a shared folder. All command line commands should be executed in the virtual machine and file modifications should be done in the host machine. It is recommended to use phpstorm.
What is Laravl
Laravel is a simple and elegant PHP Web development framework (PHP Web Framework). The share of PHP framework in the world (excluding China) exceeds 40%.
Set up the system
Check whether composer is installed. If not, please refer to composer Chinese website and modify the library to Chinese source.
Copy code The code is as follows:
composer --version
#output
Composer version 1.0.0-alpha9 2014-12-07 17:15:20
Create a Laravel project
Copy code The code is as follows:
cd /mount the shared folder in the virtual machine
composer create-project laravel/laravel learning-laravel-5 --prefer-dist
#need to wait
Test Project
Copy code The code is as follows:
cd learning-laravel-5/
#x.x.x.x is the virtual machine address
php -S x.x.x.x:8888 -t public
Host Browser Test
The above is the entire content of this article. I hope it will be helpful to everyone learning Laravel5.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
