PEAR is a collection of packages . If you wish to know more abot PEAR click here

On to the installation

This is the method we used

Download the package you require from the list of packages.
Create a folder called includes in your main directory. This is usually called something like public_html.
Create a folder for the package you have downloaded. In this case we have chosen the File package.
Unzip all of the files and upload them to your File folder that you have created.

The next important part is in the script listed below , you have to set up the path to your include file.

We created a folder called include and then another folder inside this called file and uploaded the package in there.

Code

<?php
//set this to the path of your include folder and the folder you created for the downloaded package
ini_set("include_path", '/home/www.mywebsite.com/public/include/file/' . PATH_SEPARATOR . ini_get("include_path"));
require_once 'File.php';
//enter the name of the text file to open
//this is in the same folder as the script in this example
$file = "files1.txt";
//echo the whole file
echo File::readAll($file);
?>
