How to Download & Install XAMPP & NetBeans: PHP Tutorial

What is XAMPP?

XAMPP is an open source cross platform web server, MySQL database engine, and PHP and Perl package. It is compiled and maintained by apache. The acronym XAMPP stands for;

• X – [cross platform operating systems] meaning it can run on any OS  Mac OX , Windows , Linux etc.
• A – Apache - this is the web server software.
• M – MySQL - Database.
• P – PHP
• P – Perl – scripting language

Why use XAMPP?

• In order to use PHP, you will need to install PHP, Apache and may be even MySQL. It’s not easy to install Apache and configure it. If you install Apache on its own, you will still have to set it up and integrate it with PHP and Perl among other things. XAMPP deals with all the complexity in setting up and integrating with PHP and Perl. Unlike Java that runs with the Java SDK only, PHP requires a web server to work
• XAMPP provides an easy to use control panel to manage Apache, MySQL and other programs such as Tomcat, filezilla etc. You don’t have to memorize commands for starting apache, MySQL etc.

In this tutorial, you will learn-

• How to Download and Install XAMPP
• Basic Web server configuration
• XAMPP Control Panel
• Configure XAMPP
• What is the best PHP IDE?
• Introduction to Netbeans IDE
• Creating a new PHP project using the Netbeans IDE
• Running your first PHP Example

How to Download and Install XAMPP

We look into step by step process to install XAMPP for Windows. For Other Operating Systems, installation steps are similar.

• Download the XAMPP installer at http://www.apachefriends.org/en/xampp-windows.html

• Installation XAMPP is just like installing any other windows program. There are however, a few things that we must note.

• After you have downloaded XAMPP, run the setup. The warning message dialog window shown below appears.

• If you are using windows Vista or Windows 7, make sure that you deactivate the User Account Control feature. To do this, Select Control Panel >  User Accounts >  Change User Access Control settings. The diagram below illustrates the main steps.

• After you have deactivated the User Account Control, click on OK button on the warning message box.
• This time you get following message

• In the succeeding screen, click next

• In the next screen, Change the installation path if required. Click Next

• In the next screen select Apache and MySQL. You may optionally select FileZilla (FTP Client) if needed. Click Install

Note a service is a long-running program in windows that does not require user intervention. Services can be set to run automatically whenever the windows operating system is started. For you to use Apache and MySQL, they are supposed to be running in the background. Installing them as services runs both Apache and MySQL automatically in the background whenever you power up your computer. If you have not installed Apache and MySQL as services, then you have to manually start them every time that you want to use them. You will have to do this from the XAMPP control panel.PHP and

• On successful completion of installation, you will see following window

• Click on Finish button

Before we test our XAMPP installation, let’s first look at the basic directories that we will be working with.

Basic Web server configuration

This tutorial assumes that you have installed XAMPP on drive C in Windows using the steps mentioned above. The following is a list of the basic directories that you are supposed to be aware of.

• htdocs; this is the web root directory. All of our PHP codes will be placed in this directory.
• mysql – this directory contains all the information related to MySQL database engine, by default it runs on port 3306.
• php – this directory contains PHP installation files. It contains an important file named php.ini. This directory is used to configure how PHP behaves on your server.

  By default, the Apache web server runs on port 80. If port 80 is taken by another web server, you can use a different port number. For this tutorial we will assume we are using port 80. Note,If you use SKYPE , it uses the same port. Close Skype if you want to use Apache on port 80

XAMPP Control Panel

The control panel is used to manage programs installed via XAMPP. To open the XAMPP control panel,

• Click on start menu
• Explore the programs directory and locate Apace Friends then XAMPP as shown in the diagram below

• The diagram below shows the control panel.

1)  This section lists the installed services, modules and the process IDs PID(s). A green tick means the module has been installed as a service. The red mark means it has not been installed as a service. To install a service, click on the red mark. If the button shows a green tick and you click on it, the control panel will ask you if you want to uninstall the system.

2) This section shows Port(s) associated with the modules. The actions section is for;

1.  starting and stopping modules
2. Open the administrative windows for Apache and MySQL
3. Open configuration files for Apache, MySQL etc. to make changes
4. View log files for the modules

3) This section contains useful utilities such as Netsat, windows services short cuts etc.

4) This section displays status information on the modules. The control panel can be used to;

• Install and uninstall services such as Apache, MySQL etc. that are installed via XAMPP
• Start and stop services.
• Open configure files etc.

Configure XAMPP

Let’s now look at the basic configurations required before we start using our XAMPP installation for developing PHP powered web sites. Type the URL http://localhost/xampp/ in your favorite browser. For this tutorial, we will be using Firefox as our web browser.

If you are able to see the above screen then you have installed XAMPP successfully. The panel on the left hand side contains links to useful information such as;

• The version of PHP installed
• Security settings of XAMPP
• Access to utilities such as phpMyAdmin etc.

The PHP version shipped with XAMPP 1.8.0 is PHP 5.4.4

What is the best PHP IDE?

A PHP IDE is a program that allows you to easily write PHP codes. PHP IDEs are often equipped with syntax highlighting features and in some cases autocomplete features too. This means that if you write a PHP keyword that is known by the PHP interpreter, then the keyword will be highlighted a different color from the one used for regular statements. The autocomplete features automatically pops up known PHP keywords as you type them. Notepad can also be used to write and editor PHP codes. The disadvantage of using an editor such as Notepad is that debugging the scripts becomes difficult because it is not easy to spot errors such as misspelt keywords, unclosed braces etc. an IDE will highlight the statements with errors so it’s easy for you to spot them. The table shown below shows 5 popular PHP editors

  Netbeans IDE PHP editor As briefly highlighted in the above table, Netbeans IDE has powerful features that enhance the productive of PHP coders. The IDE can be freely downloaded from the https://netbeans.org/downloads/index.html

• Syntax highlighting and auto-complete features enhances your productivity
• It has native support for database systems like MySQL. You don’t need to use two programs to code and develop your database.
• The IDE can be used in a collaborative environment. This comes in handy when you have to work with other developers as a team.
• The IDE has support for other languages such as;
  • Java SE
  • Java EE
  • C
  • C++

The current version of the Netbeans IDE as of this writing is version 7.3

Introduction to Netbeans IDE

After you have successfully installed the Netbeans IDE PHP editor, run the program just like any other windows program. The window shown below appears

1. Project explorer – this panel is used to display all the opened projects. The projects are listed in a tree view.

2. Shortcuts tool bar – this toolbar contains shortcuts to frequently performed tasks such as creating a new project, opening an existing project, undo and redo actions etc.

3. Startup page – this page contains 3 tabs namely- Learn & Discover, My Netbeans and What’s New.

• The first tab [Learn and Discover] introduces you to the features of the Netbeans IDE, showcases some demos and tutorials that can be developed in the Netbeans IDE.
• The second tab [My Netbeans] lists the recently opened projects, allows you to install plugins and activate features of the IDE.

4. Output window – it is used to display output from programs such as Java console applications. It is also used to display log and debug information. The screenshot below shows the IDE with a project open.
