Configuring PHP

Once PHP is successfully installed, we still need to configure it some. Here is a simple example of a configuration file:

sudo nano /etc/php/7.0/apache2/php.ini

Copy after login

You can change the file name depending on the version of PHP you are using and the type of web server.

The following are some common settings for PHP configuration files:

display_errors = On: Output PHP errors to the browser.
error_reporting = E_ALL: Causes PHP to throw all errors.
upload_max_filesize = 10M: Allows uploading files up to 10MB.
post_max_size = 10M: Set the maximum post data to 10MB.

Install PHP extensions

PHP supports many extensions (such as gd, xml, mysql, mysqli, etc.). If you need to use some extensions for PHP, please follow these steps to install them:

Open a terminal and switch to superuser:
```
sudo su
```
Copy after login
Copy after login
Copy after login
Install the required extensions:
```
apt-get install php-<extension>
```
Copy after login
Restart the web server:
```
service apache2 restart
```
Copy after login

Note: We only use apt-get command to install here Extension, since Ubuntu and Debian use the APT package manager. If you are using another Linux distribution, you will need to check the relevant documentation for installation steps for the extension.
