In order to install NetBeans IDE, you must download it, free of charge, from the following address:

https://netbeans.org/downloads/index.html

On the NetBeans web page, there is a dropdown list that lets you choose the required platform (Windows, Linux, or Mac OS X). Choose the platform that matches yours. This article shows the process of installing NetBeans IDE on a Windows platform.

From all the “download bundles” available on netbeans.org, select and download the one called “All.” When the download is complete, run the corresponding installer.

If you receive the message shown in Figure 1, it means that the Java SE Development Kit (JDK) was not found on your system. Please click here to download and install the JDK before proceeding with the NetBeans IDE installation.

In the “PHP 5 Interpreter” field, specify the path to the “php.exe” file. Use the “Browse…” or “Search…” button, if necessary. If you haven’t already changed XAMPP’s folder during the installation process, this path should be “c:\xampp\php\php.exe.”

Notice: If XAMPP is not installed on your system, read and follow the instructions shown here.

You can also change the number of spaces per indent to two by clicking on the Editor icon to open the Editor’s “Options” dialog box, as shown in Figure 8. On the “Formatting” tab, set the field “Number of Spaces per Indent” to 2.
