Help needed to tag words with score

[kailash001]

Hello guys, i need some help in assigning a score to a word according to its occurrence in a group of sentences.

[code=php:0]
$words="Hello, how are you?";
$sentences="Hello! I am fine. How about you? You look good.";

[/code]

now i'm trying to assign a score to each word in $words e.g Hello=1, how=1, are=0, you=2.

I'm not sure exactly how to do this, but I would approach it this way.

 

You would have to parse the string, and break up each of the individual words. Then you would need to compare each individual word to a db of words that you have. When a match is found, then pull the score for that word..

 

Might be an easier way, but I'm not sure?

ok so i made some modifications

<?php
$words="Hello how are you";
$word_array = explode(" ", $words);

$paragraph="Hello! I am fine. How about you? You look good.";
$sencetences = strtok($paragraph, ".!?");  
?>

now i have all the words in an array and the sentences are separated. i don't want to compare the words from DB but check its occurrence in the paragraph then assign the score to it. the score is in fact the number of times it is repeated in the paragraph.

Wouldn't you explode the paragraph into another array, and then you could compare the arrays, iterating through them looking for matches..
