Question

I have a table in MySql with several different fields, one of them contains a description that could be a couple of paragraphs long.

I am trying to figure out a way to have php automatically go through these description fields and create a list of the top keywords used. I am looking for the top keywords for the entire table, not each post individually.

I know this is a bit of a resource heavy operation, and it wouldn’t be run very often anyways.

But I’d like to get a list like this:

some x 121
most x 110
frequent x 90
words x 50

So that I could see what the top used words are in the description field. Any idea at all where to start?

Answer 1

You can run you query,

1. loop through the records and append descriptions together into 1 big happy string.

2. Then, you can explode by ‘ ‘ into array

3. Get array of values using array_count_values()

4. Re-sort in descending order arsort()

Update

Sample code too:

$string = '';
foreach (your_result_set as one_row) 
{
    $string .= $one_row['text'];
}

$data = explode(' ', $string);
$data = array_count_values($data);
arsort($data);
