storing in array and retreving..

[kishore2k9]

hi,
I am developing the word cloud. I have to convert the word its ending with ed,s,ies,ing.
like ex: provide,providing,provided. it should convert to provide..

ex2://my current array contains following keys & values
$arr1=array("provide"=>1,"killed"=>2,"provided"=>1,"kill"=>1,"providing"=>1,"killing"=>1);
from the above array i have to get the output as
array("provide"=>3,"kill'=>4);

You would need some sort of dictionary database, so that you could somehow determine that "providing" becomes "provide" but "something" does not become "someth".
