Meta Keyword Generator

[phpmine]

Hello you freaks! I am looking to make an automatic meta keyword generator based on an array of phrases. It is more my site that is under construction, http://www.phpmine.com. Go to the "Q and A" section and you'll see a series of questions there, five in total. right now the system simply grabs all the words there, filters though common words, and then spits out the words as keywords. I would like some advice on how to set it up in this way:

• puts all the words in an array  and counts their frequency
  
• creates an array of two words phrases and counts their frequency
  
• does the same for 3 word phrases
  
• spits out the top 25 keywords from the array generated
  

 

maybe someone has already cokked up this nasty script. thanks in advance guys!

I can't really write this for you right now (I'm at a conference), but you'd use array_count_values to get the frequencies, and the rest is pretty easy.

WOW! that was a fast reply! love the community already. yeah i did that for the frequency of the words, but how do i build an array of all the 2 word phrases found? the logic of the scripts does not hit me right away.

Define "two word phrases".  Like, just groupings of any two words, i.e:

 

You have:

"The sky is quite blue today.";

 

You want:

"The sky"

"sky is"

"is quite"

"quite blue"

"blue today"

 

Right?

right! then i would count their frequency.
