sudo apt install php libapache2-mod-phpDuring the installation process, you may be prompted to enter your password to confirm the installation. Once the installation is complete, PHP will be installed and configured to work with Apache.
To verify that PHP has been installed successfully, you can create a PHP info file. Open a text editor and create a file called “info.php” with the following content:
<?php
phpinfo();
?>Save the file and move it to the Apache document root directory, “/var/www/html” by running the following command:
sudo mv info.php /var/www/html/Now, open your web browser and enter “http://localhost/info.php” or “http://your_server_IP_address/info.php” in the address bar. If PHP is installed correctly, you will see a page displaying detailed information about your PHP installation.
You can also test PHP by running a simple script. Open a text editor and create a file called “test.php” with the following content:
<?php
echo "Hello, PHP!";
?>Save the file and move it to the Apache document root directory using the following command:
sudo mv test.php /var/www/html/Now, open your web browser and enter “http://localhost/test.php” or “http://your_server_IP_address/test.php” in the address bar. If PHP is working correctly, you will see the text “Hello, PHP!” displayed on the page.
Congratulations! You have successfully installed PHP on your Ubuntu 22.04 system and tested its functionality. In the next step, we will explore how to install additional PHP modules to enhance its capabilities.
Step 4: Verify PHP installation
After installing PHP on your Ubuntu 22.04 system, it is essential to ensure that it has been installed correctly and is functioning as expected. In this step, we will perform some basic tests to verify the PHP installation.
To begin, open a terminal and navigate to the Apache document root directory (/var/www/html) by running the following command:
cd /var/www/htmlNext, create a file called “phpinfo.php” using a text editor with the following content:
<?php
phpinfo();
?>Save the file and exit the text editor. This file will output detailed information about your PHP installation when accessed through a web browser.
Now, open a web browser and enter “http://localhost/phpinfo.php” or “http://your_server_IP_address/phpinfo.php” in the address bar. If PHP is installed and configured correctly, you should see a page with extensive information about your PHP version, configuration settings, loaded modules, and more.
In addition to the PHP information page, you can also test PHP by creating a simple script. Create a new file called “test.php” in the same directory (/var/www/html) and add the following code:
<?php
echo "PHP is working!";
?>Save the file and close the text editor. Then, open your web browser and navigate to “http://localhost/test.php” or “http://your_server_IP_address/test.php”. If PHP is functioning correctly, you should see the text “PHP is working!” displayed on the page.
These steps help ensure that PHP is installed and functioning properly on your Ubuntu 22.04 system. If you encounter any issues or errors, double-check the installation steps and configuration settings to troubleshoot the problem.
With PHP successfully installed and verified, you are now ready to develop dynamic and interactive web applications on your Ubuntu 22.04 system. However, to expand the functionality of PHP, you may want to install additional PHP modules, which we will cover in the next step.

However, depending on your specific project requirements, you may need to install additional PHP modules to enhance its capabilities. This step will guide you through the process of installing additional PHP modules on your Ubuntu 22.04 system.
To install a PHP module, you can use the apt package manager followed by the name of the desired module. For example, to install the MySQL module, run the following command in the terminal:
sudo apt install php-mysqlReplace “mysql” with the specific module you want to install. Some common PHP modules include “php-gd” for image processing, “php-curl” for URL manipulation, and “php-xml” for XML parsing support.
During the installation process, you may be prompted to enter your password to confirm the installation. Once the installation is complete, the module will be automatically configured and ready to use.
To ensure that the module has been successfully installed and enabled, you can create a PHP script that checks for its presence. For example, create a file called “module_check.php” and add the following code:
<?php
if (extension_loaded('module_name')) {
echo "The module is installed and enabled!";
} else {
echo "The module is not installed or enabled!";
}
?>Replace “module_name” with the name of the module you installed. Save the file and move it to the Apache document root directory (/var/www/html).
Open your web browser and enter “http://localhost/module_check.php” or “http://your_server_IP_address/module_check.php” in the address bar. If the module is installed and enabled correctly, you will see the message “The module is installed and enabled!” displayed on the page. Otherwise, you will see “The module is not installed or enabled!”.
Repeat these steps for each additional PHP module you want to install. Remember to test each module individually to ensure it is functioning as expected.
Installing additional PHP modules allows you to expand the capabilities of PHP, enabling you to work with various databases, perform advanced image processing, interact with external APIs, and more. Take advantage of these modules to streamline your development process and achieve your desired functionality.
