The key steps to deploy the PHP framework to apply to the server include: 1. Prepare the server environment and ensure that PHP, Web server, database, Composer and necessary extensions are installed; 2. Upload code and install dependencies. It is recommended to use Git. Laravel also needs to generate keys and cache configurations; 3. Configure the web server to the entry file, both Nginx or Apache can be used; 4. Set up the database connection and run migration and seed. The entire process needs to pay attention to permission settings and log checking to troubleshoot problems.

Deploying a PHP framework to apply to a server is not complicated, but there are several key points that need to be paid attention to. Different frameworks (such as Laravel, Symfony, CodeIgniter) may differ slightly, but the overall process is roughly the same.

1. Prepare the server environment

Before starting deployment, make sure your server has the necessary running environment installed:

• PHP : Confirm whether the version meets the framework requirements (for example, Laravel 9 requires PHP 8.0)
• Web server : Nginx or Apache are both OK, depending on which one you are used to
• Database : MySQL, PostgreSQL, etc., installed according to project requirements
• Composer : for dependency management, which is dependent on by almost every modern PHP framework
• Other extensions : For example, common PHP extensions such as openssl , mbstring , tokenizer , etc. must also be enabled.

You can check PHP version and extension via commands:

 php -v
php -m | grep mbstring

2. Upload the code to the server

There are several ways to do this, depending on how you manage the project:

• Use Git to clone repositories (recommended):

   git clone https://your-repo-url.git /var/www/your-app

• Upload local files using FTP/SFTP
• Automatic deployment using CI/CD tools (such as GitHub Actions, GitLab CI)

After uploading, go to the project directory to execute the Composer installation dependency:

 cd /var/www/your-app
composer install --optimize-autoloader --no-dev

If it is a framework like Laravel, you also need to generate a key and configure a cache:

 cp.env.example.env
php artisan key:generate
php artisan config:cache
php artisan route:cache
php artisan view:cache

Don't forget to set storage directory permissions:

 chmod -R 775 storage bootstrap/cache

3. Configure the web server to point to the entry file

The entry file for most PHP frameworks is /public/index.php , so you need to point the root directory of the web server to this location.

If using Nginx:

Edit the site configuration file (usually located in /etc/nginx/sites-available/default or similar path):

 server {
    listen 80;
    server_name yourdomain.com;
    root /var/www/your-app/public;

    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php-fpm.sock;
    }
}

Restart Nginx after saving:

 sudo systemctl restart nginx

If using Apache:

Make sure that the .htaccess file exists and mod_rewrite is enabled so that the URL rewrite can work properly.

4. Set up database connection

Modify the database configuration information in the .env file to ensure that it can be connected to the database on the server:

 DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_db_user
DB_PASSWORD=your_password

If you are using a framework such as Laravel, remember to run the migration:

 php artisan migrate

If there is seed data that needs to be imported, you can also add:

 php artisan db:seed

Basically that's it. The deployment process seems to have many steps, but as long as you take it step by step, there is no big problem. Be careful to check log files (such as Nginx's error.log and framework's logs), and they provide clues when encountering problems.
