5ch info:Redirect old URL

Since there are many links to old URL, it is good to redirect to new URL.

http://info.2ch.net/wiki/pukiwiki.php?page=EUC-JP encoded title

http://info.2ch.net/wiki/index.php?EUC-JP encoded title

http://info.2ch.net/wiki/index.php?page=EUC-JP encoded title

/wiki/index.php

<?php
## Setting
$NewUri = 'http://info.2ch.net/index.php/';
$NewTopPage = '%E3%83%A1%E3%82%A4%E3%83%B3%E3%83%9A%E3%83%BC%E3%82%B8'; # Main page


## Get title
# ?page=title
if ( $Title = $_REQUEST['page'] ) {

# ?title
# ?command=value is excepted
} else if ( $_SERVER{'QUERY_STRING'} && strpos($_SERVER{'QUERY_STRING'}, '=' ) === false ) {
	$Title = $_SERVER{'QUERY_STRING'};
}


## Replace title
switch ( $Title ) {
	case '%A3%B2%A4%C1%A4%E3%A4%F3%A4%CD%A4%EBWiki' : # Top page
	case 'RecentChanges' : # Special page
	case 'RecentDeleted' # Special page
	case 'Help' : # Special page
	case 'HowToEdit' # Guide
	case '%A5%DA%A1%BC%A5%B8%CA%D4%BD%B8%A4%CE%C0%E2%CC%C0%BD%F1' # Same as HowToEdit
	case '' :
		$Title = $NewTopPage;
		break;

	default :
		# EUC-JP to UTF-8
		if ( strpos($_SERVER{'QUERY_STRING'}, '%' ) !== false ) {
			$Title = urldecode($Title);
			$Title = mb_convert_encoding($Title, 'UTF-8', 'EUC-JP');
			$Title = str_replace(' ', '_', $Title);
			$Title = urlencode($Title);
		}
}
