Method 1

Method 2
Alternatively enter the following into your browser:

Using PEAR Frontend

Open the PEAR front-end using one of the methods explaind above.

Installing PEAR packages is very easy. To confirm our PEAR installation is working and to demonstrate how to install packages, we will be using a package named HTML_QuickForm

Update the Channel Management system

Before downloading any package, update the Channel Management system

  • C) Click on Channel Management - Opens Registered Channels page.

Downloading modules

Downloading a known package (example HTML_QuickForm)

  • A) Click on Package Management - Opens management page.
  • Scroll down page to Quick-install a package
  • Enter package name HTML_QuickForm
  • Click Install
 Auto PEAR Install
  • After a short time the package is installed.
  • Note the Warnings! We know this is an older package but want to use it anyway.
 Auto PEAR Install
  • A) Click on Package Management - Opens management page.
  • New Installed packages are listed.

Although we intended to only download and install a single package, two were installed. The package HTML_QuickForm will not function without package HTML_Common; it depends on this being in place. In other words, when installing a package, all dependencies that do not exist are also installed.
