Step 4: Check Version

After successful installation, you can check the current installed version by using php --version command as shown below.

cyberithub@ubuntu:~$ php --version
PHP 8.1.2-1ubuntu2.11 (cli) (built: Feb 22 2023 22:56:18) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
with Zend OPcache v8.1.2-1ubuntu2.11, Copyright (c), by Zend Technologies

 

Step 5: Using PHP

Now that PHP is installed, it is time to write a sample script to test the utility. Here we are going to create a simple example.php script using nano example.php command as shown below.

cyberithub@ubuntu:~$ nano example.php
<?php
phpinfo()
?>

When you run above script using php example.php command then it will show output like below. This confirms that PHP is working fine in your System.

cyberithub@ubuntu:~$ php example.php
phpinfo()
PHP Version => 8.1.2-1ubuntu2.13
