Text Help

Rayn

Hi,

I need help with trying to figure out how to get the most used words out of a text block. Not to sure how to describe this so I will give a example.

$mes01 = "Hi my name is Rayn and I like this and that and them and her"

$mes02 = "Where are we? Why are we here? What is going on?"

// code I need help with

output:

and
are
is
we

etc..

And I would like to be able to limit how many it outputs.. like instead of 4 have 3 or 5 and so on.

Thanks for your time

Is it possible to create an array with those type of words and use something like the preg_match_all() function to find the words from the array?

// Quick and dirty example

$words = array('and', 'are', 'is', 'we');

$mes01 = "Hi my name is Rayn and I like this and that and them and her";
$mes02 = "Where are we? Why are we here? What is going on?"; 

$found = array();

for($i=0; $i<count($words); $i++) {
    preg_match_all('/'.$words[$i].'/i',$mes01.$mes02,$matches);

for($j=0; $j<count($matches[0]); $j++)
    array_push($found,$matches[0][$j]);
}

print_r($found);

the purpose of this is to get the top words used in any kind of text.

So if someone enters:

the the the and the

it will output

the (4)
and (1)

and it will do this up to a certain amount of words... like a top 5 list or such.

Thanks

array_count_values() could be useful.

there are different ways to split a string to get an array of words, preg_match_all is just one:

// you can add more characters you'd like to allow into the square brackets
preg_match_all('/[a-zA-Z]+/', $string, $matches);

$counts = array_count_values($matches[0]);

print_r($counts);
// now you could sort the array and print the top x only

I haven't tested this, but this is how I'd try.
