Count the number of occurrences of a string in a VARCHAR field?

Question

I have a table like this:

TITLE          |   DESCRIPTION
------------------------------------------------
test1          |   value blah blah value
test2          |   value test
test3          |   test test test
test4          |   valuevaluevaluevaluevalue

I am trying to figure out how to return the number of times a string occurs in each of the DESCRIPTION's.

So, if I want to count the number of times 'value' appears, the sql statement will return this:

TITLE          |   DESCRIPTION                  |   COUNT
------------------------------------------------------------
test1          |   value blah blah value        |   2
test2          |   value test                   |   1
test3          |   test test test               |   0
test4          |   valuevaluevaluevaluevalue    |   5

Is there any way to do this? I do not want to use php at all, just mysql.

This should do the trick:

SELECT 
    title,
    description,    
    ROUND (   
        (
            LENGTH(description)
            - LENGTH( REPLACE ( description, "value", "") ) 
        ) / LENGTH("value")        
    ) AS count    
FROM <table>
