 Configure PHP 8.4 or 8.3 (Optional)

We can modify PHP settings by editing the `php.ini` file. The file’s location depends on whether PHP is being used for the command line or a web server:

Command Line:
PHP 8.4: ‘/etc/php/8.4/cli/php.ini’
PHP 8.3: ‘/etc/php/8.3/cli/php.ini’

Web Server (Apache/Nginx):
PHP 8.4:
Apache: ‘/etc/php/8.4/apache2/php.ini’
Nginx (PHP-FPM): ‘/etc/php/8.4/fpm/php.ini’
PHP 8.3:
Apache: /etc/php/8.3/apache2/php.ini
Nginx (PHP-FPM): /etc/php/8.3/fpm/php.ini

To edit the ‘php.ini‘ file, use a text editor like `vi` or `vim`:

For PHP 8.4 (Command Line):

$ sudo vi /etc/php/8.4/cli/php.ini

For PHP 8.3 (Command Line):

$ sudo vi /etc/php/8.3/cli/php.ini

max_execution_time = 300

memory_limit = 512M; 

post_max_size = 80M;

upload_max_filesize = 50M; 

date.timezone = Asia/Dhaka

systemctl restart apache2

Configuring Nginx Server Block for PHP-FPM 8.2

Modify the Nginx server block to process PHP files. Add this to the relevant server blocks:

location ~ .php$ {

    include snippets/fastcgi-php.conf;

    fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;

}

You can validate the syntax of your modified Nginx configuration using the following command:

sudo nginx -t

This command verifies the syntax of the configuration files and highlights any errors found. A successful output will look like this:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

Once you’ve confirmed the syntax is correct, restart the Nginx service to apply the changes:

sudo systemctl restart nginx

As a final note, always ensure you check the version of PHP installed on your system. Use the following command to do this:

php --version
