If you are running an Apache web server on your Linux system and find that PHP files are not being executed, there are a few potential solutions that can help with this problem. PHP is a common component of web server setups, and is the programming langauge used by WordPress, the most popular content management system in the world. It is commonly installed alongside Apache and MySQL, which is known as LAMP (Linux, Apache, MySQL, PHP).

How to install PHP on Ubuntu Linux
PHP is one of the most used languages when it comes to programming dynamic web sites. If you are a web developer, or just hosting a website that requires PHP, you will need to install the software on your server in order for your website to make use of its PHP code.

A LAMP stack is an assortment of software that contains everything you need in order to serve a website, show dynamic content, and store or retrieve data from a database. The software is all within the LAMP acronym, namely the Linux operating system, Apache web server, MySQL database (or MariaDB alternatively), and PHP programming language.
How to install XAMPP on Ubuntu Linux
Hosting a website on a Linux system usually involves multiple software packages that operate together to deliver a web browsing experience to potential viewers. For example, it’s common for PHP to dynamically render web content but retrieve data from a database. These are two separate components and they must both be installed to present a website as intended.
XAMPP is a software stack that can run on Ubuntu Linux and make your life a little easier when it comes to web hosting. XAMPP stands for cross-platform (X), Apache (A), MariaDB (M), PHP (P), and Perl (P). These are all common components used in web hosting, and combining them into a single installation makes the initial setup less complicated. XAMPP also comes with Bitnami, which allows you to install content managements systems, such as WordPress, as well as other apps on top of your XAMPP installation if you choose.
In this guide, we’ll cover the installation of XAMPP on Ubuntu Linux. Follow along with our step by step instructions to get it setup on your own system.

How to enable sessions in PHP with cookies
Cookies are all around in our everyday life while we browse the Internet. Most people wouldn’t know much about them, if not for those “our website uses cookies to be operational” signs that are on mostly any page now since GDPR. Cookies have a long history if sometimes being good, sometimes bad. As it is usual with most aspects of the world, this technology can be used in a good or bad way.
In this tutorial we will explore cookies a bit from the server side programming perspective: we’ll create an example cookie in PHP, and store the visitor’s chosen username in it. The cookie will reside in the browser of the visitor, so on the next visit we can read it and use it to greet the visitor on the username submitted.
Our simple webpage will recognize the visitor as long as the cookie is present in the browser. We do not store any information on the server side: if the visitor first checks in from a PC, and next time from a smartphone, we will not know it is the same individual. This is one of the main point with cookies: we can only identify the given client, and only as long as the data is provided by that particular browser.
In this tutorial you will learn:
- How to setup the test environment
- How to write a simple example program that uses cookies
- How to test the workings of the program
- How to reset the environment

Introduction
Laravel as quickly earned its place as the top PHP framework. It brought a lot of developer friendly features found in other frameworks like Rails to the PHP ecosystem, and in doing so, modernized PHP development.
If you’re looking to develop with Laravel or host it on Ubuntu 18.04, the setup process has never been easier. Since Laravel is PHP, there are a couple of ways to handle this, but Nginx and MariaDB provide a fairly straightforward way to get your project running with modern production-ready tools.
