Question by Jamie T:
Word frequency PHP Count On Text File?
Hi There,

I’m running a search engine for media files and I am trying to script a box with the 50 most popular search terms. My search engine currently has a text file which the site writes to each time someone searches a term. So all I need is a code to count the frequency of the terms in the text file and the 50 most popular need to be written (automatically) into the homepage of my site. Any help?

You might think about using a db table to do this more efficiently. Each time someone searches you check to see if the term is already in a table, in which case you increment a counter field. If it’s not there, you add it with the counter field set to initial value of 1. Use an index on the counter field and the time needed to get top 50 is greatly reduced because you will not be processing that text file.

# Start non-www page protection #

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.mysite\.com [NC]
RewriteRule ^(.*)$ http://www.mysite.com/$ 1 [L,R=301]

# End non-www page protection #

Is this the correct format, and will all links now point just to the www version just from the time that I do this and upload the new .htaccess file, or will all links (and the page rank boost associated with it) become retrospective? Will I see a boost in rank immediately?

I’ve also heard that the search engines see a www.mysite.com version and a www.mysite.com/ version. Will my script take care of this as well, or do I have to add something else? (I cannot see whether the script does this or not as I am not a coder!)

For .co.uk domains do I just alternative .co.uk for .com in each case?

RewriteEngine on
RewriteCond %{HTTP_HOST} ^yourdomain\.co.uk$ [NC]
RewriteRule ^(.*)$ http://www.yourdomain.co.uk/$ 1 [R=301,L]

That above is the only code you need to redirect non-www to www in your .htaccess file. Yes you can change *.com to *.co.uk to get the same results, I made the code already valid for that. Change “yourdomain” to your domains name.

Yes, this will prevent duplicate content issues with search engines regarding two URLs having the same content. All non-www requests will be 301 redirected to their www counterpart. Results will take time, you might not even yeild none but a more proper internal link structure.

No they can’t.

You could however use something like RewriteCond to detect the user-agent string Mozilla and then rewrite robots.txt to some other file. You would have to exclude the two or three bots that include Mozilla in the user-agent string though. Simple enough but why would you want to do this?

I would advocate you to create a table in a database that might have the following fields :
id (unique identifier, you might use it to update data),
url (the location of the file on your server),
title (to identify it),
description (to describe what is in the file),
keywords (words you might use to search the file)
date (date of insertion).

And when you want to search for a file, the search will be made in the database. You will be able to see the details such as description etc.
And when you click on it, you will be able to go to the file you want by using the field URL that is in the DB.

It will be faster this way. All you have to do in the DB is inserting new file, you do not have to make your script do too much for nothing.
