Can i run php on ubuntu?

PHP - Scripting Language

PHP is a general-purpose scripting language suited for Web development. PHP scripts can be embedded into HTML. This section explains how to install and configure PHP in an Ubuntu System with Apache2 and MySQL.

This section assumes you have installed and configured Apache2 Web Server and MySQL Database Server. You can refer to the Apache2 and MySQL sections in this document to install and configure Apache2 and MySQL respectively.

Installation

PHP is available in Ubuntu Linux. Unlike Python, which is installed in the base system, PHP must be added.

To install PHP and the Apache PHP module you can enter the following command at a terminal prompt:

sudo apt install php libapache2-mod-php

You can run PHP scripts at a terminal prompt. To run PHP scripts at a terminal prompt you should install the php-cli package. To install php-cli you can enter the following command:

sudo apt install php-cli

You can also execute PHP scripts without installing the Apache PHP module. To accomplish this, you should install the php-cgi package via this command:

sudo apt install php-cgi

To use MySQL with PHP you should install the php-mysql package, like so:

sudo apt install php-mysql

Similarly, to use PostgreSQL with PHP you should install the php-pgsql package:

sudo apt install php-pgsql

Configuration

If you have installed the libapache2-mod-php or php-cgi packages, you can run PHP scripts from your web browser. If you have installed the php-cli package, you can run PHP scripts at a terminal prompt.

By default, when libapache2-mod-php is installed, the Apache 2 Web server is configured to run PHP scripts using this module. Please verify if the files /etc/apache2/mods-enabled/php8.*.conf and /etc/apache2/mods-enabled/php8.*.load exist. If they do not exist, you can enable the module using the a2enmod command.

Once you have installed the PHP related packages and enabled the Apache PHP module, you should restart the Apache2 Web server to run PHP scripts, by running the following command:

sudo systemctl restart apache2.service 

Testing

To verify your installation, you can run the following PHP phpinfo script:

<?php
  phpinfo();
?>

You can save the content in a file phpinfo.php and place it under the DocumentRoot directory of the Apache2 Web server. Pointing your browser to http://hostname/phpinfo.php will display the values of various PHP configuration parameters.

How to run PHP on Ubuntu.

First of all you will need a web-server to host our PHP pages.

In this tutorial I ll use Apache2. You can install Apache2 from the Terminal by using:

sudo apt-get update
sudo apt-get install apache2

when the installation is finished, Apache is up and running and you can test that by pointing your web browser at http://localhost/

The default page will come up with a message "it works" and some more info.This html file is located under your local file system in folder /var/www/html/

Now you have to install PHP.

To install PHP and PHP support for Apache, just write the following in console:

sudo apt-get install php

When this is done you are ready.

Let’s go and replace the default page of Apache so we can create our own.

Open a terminal and type:

sudo mv /var/www/html/index.html /var/www/html/index.back

If you want to test that PHP is installed successfully into your system you can write and run a simple PHP script that will return to you the PHP information. So open the terminal and type:

sudo gedit /var/www/html/index.php

An empty document will open in gedit now just type the following and save the document.

<?php
print_r (phpinfo());
?>

And point your web browser at: http://localhost/

You should now be able to see your first PHP page running.

You can edit this page at any time by typing:

In order to restart Apache web server just type the following command

sudo gedit /var/www/html/index.php

In this tutorial im using gedit to create my webpages but you can also install an IDE like netbeans and manage you projects from there in a way more efficient way. Check the installation process of Netbeans here.

If you also need MySQL you can find info on how to install MySQL here.

Have fun creating your web pages!
