Uniform Server Portable PHP IDE.

Installing Notepad++, NppExec plugin and DBGP plugin

Core component of this portable PHP IDE is Notepad++ it is inherently portable this page shows how to install it for both portable and USB use.

It also covers installing plugins NppExec and DBGp. Plugin NppExec is required for running PHP scripts it installs an integrated console window allowing commands to be entered and display output from PHP CLI scripts. Plugin DBGp interfaces to the PHP XDebug extension allowing debugging of PHP scripts.

Although Notepad++ is relatively small for a plugin it is larger than we require hence the basic core is extracted and only plugins mentioned above are used. This results in a smaller compact IDE.


Create two new folders

On C drive create two new folders

  • Step 1) Create folder c:\us_portable_ide
  • Step 2) Create folder c:\us_portable_ide_temp

These can be named whatever you like. Our portable IDE will be created in folder us_portable_ide. To save space folder us_portable_ide_temp can be deleted on completion.

Download and extract Notepad++

Download latest version ( of Notepad++ from SourceForge or from

Save downloaded file to folder c:\us_portable_ide_temp (or whatever you named it)

Right click on file ( and select Extract all files, no need to change path. After extraction you will find two versions of notepadpp ansi and Unicode contained in the following folders:

  • c:\us_portable_ide_temp\npp.5.8.4.bin\ansi
  • c:\us_portable_ide_temp\npp.5.8.4.bin\Unicode

The “ansi” version is older and will eventually be phased out hence always use newer “Unicode” version.

Step 3)

  • Copy folder: c:\us_portable_ide_temp\npp.5.8.4.bin\Unicode
  • To folder: c:\us_portable_ide

Delete unwanted folders and files

Default Notepad++ size is around 10.0 MB we want to reduce this by removing unwanted folders and files as follows:

  • Navigate to folder C:\us_portable_ide
  • Delete folder C:\us_portable_ide\updater
  • Delete folder C:\us_portable_ide\themes
  • Delete folder C:\us_portable_ide\localization

  • Navigate to folder C:\us_portable_ide\unicode\plugins
  • Delete all files in this folder (ComparePlugin.dll,NppExport.dll,NppFTP.dll,NppTextFX.dll,PluginManager.dll and SpellChecker.dll)
  • Delete folder C:\us_portable_ide\unicode\plugins\doc
  • Delete folder C:\us_portable_ide\unicode\plugins\Config\tidy

  • Navigate to folder C:\us_portable_ide
  • Delete folowing files:
    • change.log
    • NppHelp.chm
    • readme.txt

Note 1: This IDE is going to be published hence license.txt is retained and any other licences.

Note 2: Notepad++ size is now around 3.14 MB I think you will agree a significant decrease.


Running Notepad++

We want a portable development environment to achieve this we use a batch file to start Notepad++. Advantage of this it allows start-up parameters to be passed.

Create batch file start_notepad.bat

  • Create a new text file with content shown on right:
  • Save this text file to folder C:\us_portable_ide with name Run_IDE.bat
start unicode\notepad++.exe -multiInst -nosession


  • Navigate to folder C:\us_portable_ide
  • Run notepad++ double click on file Run_IDE.bat.
  • Check notepad++ starts
  • When challenged by your firewall allow access.

Note: Parameters passed

  • -multiInst Allow more than one instance of Notepad++ to be run
  • -nosession Prevents session being saved hence does not remember currently
    open files when notepaddpp is closed. Avoids incorrect file paths when portable
    development environment is moved.


New files created

Running Notepad++ create the followig new files:

  • config.xml - This instances configuration, tracks user configuration changes
  • langs.xml - Default language English
  • shortcuts.xml - Contains default entries for Run drop-down menu (We change these later)


Install plugins

Install NppExec plugin

This plugin is required to run our PHP scripts displaying the results in an integrated console window. We will configure this plugin latter.


Download the latest version of NppExec from SourceForge using the following link


  • Close Notepad++
  • Download the zip file or newer and save to folder C:\us_portable_ide_temp
  • Right click on and select Extract all files.
  • Navigate to folder C:\us_portable_ide_temp\NppExec_041_dll_Unicode
  • Copy file NppExec.dll to folder C:\us_portable_ide\unicode\plugins


Install DBGP Plugin

This plugin interfaces to the PHP XDebug module. It allows both PHP CLI and PHP web pages to be debugged. Installs an integrated user interface (window). We will configure this plugin latter.


Download the latest version of NppExec from SourceForge using the following link


  • Close Notepad++
  • Download the zip file or newer and save to folder C:\us_portable_ide_temp
  • Right click on Extract all files.
  • Navigate to folder C:\us_portable_ide_temp\DBGpPlugin_0_12b_dll
  • Copy file dbgpPlugin.dll to folder C:\us_portable_ide\unicode\plugins



At this stage all that’s required is to check both plugins are installed

  • Start Notepad++ (double click on Run_IDE.bat)
  • A) Click on Plugins. Drop-down menu shows items DBGp and NppExec  
  • B) Debugger icon. Click to display debugger window.
  • C) Show Console Dialog icon. Toggles console dialog window.

That completes installation of Notepad++ along with its plugins. Interestingly the size is relatively small around 5.0 MB.

We want an independent portable PHP CLI IDE environment. This requires installing a version of PHP next page covers installing PHP
