Step 5: Test PHP
After the installation is complete, use the following command to test Is PHP working properly:
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php
This command will create a file called info.php and place it in the web root directory of the Apache server, which contains information about the PHP version, installation options, and configuration settings information.
Now, enter the following address into the address bar of your web browser (assuming your server IP is 192.0.2.1):
http://192.0.2.1/info.php
