Question

I have an array with a bunch of words. E.g:

array( developer,develop,development,design,designer,designing )

I want to be able to group these words together with their similar words so I’d get something like this:

array(
   array( develop, developer, development ),
   array( design, designer, designing ),
);

What would be the best way to do this in PHP?

Answer 1

You can do it easily using metaphone():

$result = array();
foreach ($array as $word) {
    $result[metaphone($word, 2)][] = $word;
}

print_r($result); will show:

Array
(
    [TF] => Array
        (
            [0] => developer
            [1] => develop
            [2] => development
        )

    [TS] => Array
        (
            [0] => design
            [1] => designer
            [2] => designing
        )
)
