Q:

Parse error: syntax error, unexpected 'include' (T_INCLUDE) in D:\learnphp\drupal-7.43\site\index.php on line 31

I have search through Parse error and I didn't see T_INCLUDE. So
  I can't solve this problem.

I use .htaccess file for php and I solve the PEAR problem. After that I got another problem as you can see in title. Please somebody tell me how to solve that error.
<?php

// Start the session.
session_start();

// Moved functions to their own file so we can use them in page files.
include('includes/functions.php');

// Connect to the database.
db_connect();

// If this is index.php, we won't get a path, so we need to set it.
$path = isset($_GET['path']) ? $_GET['path'] : 'home.php';

// Render featured products.
$featured_product_output = render_product(get_setting('featured_product_ids'));

// Get some variable to use in the templates.
$company_name = get_setting('company_name');
$year = date('Y');

// Show log in / log out links.
$login_logout = '<a href="login.php">Log in </a>';
if (isset($_SESSION['user'])) {
    $login_logout = '<a href="login.php"My account</a> | <a href="login.php?action=logout>Log out</a>';
}

// Include the file that matches the path name.
require 'C:\Program Files (x86)\DevDesktop\common\pear\PEAR.php'
include('pages/' . $path);

$notices = get_notices();

include('includes/page-template.php');

A:

you forgot to write ';' at the end of line 30:
require 'C:\Program Files (x86)\DevDesktop\common\pear\PEAR.php'
