Get the combinations of words

[infinitizon]

I have an array like this

$myArray = array('a', 'b', 'c');

I want to get all combinations like so

a b c
a c b
b a c
b c a
c a b
c b a

Notice it is only a combination of the individual elements in the array (no individuals or doubles).

Any ideas please

Think about it.

you might look at the pear combinatorics class.

there are a number of ways to solve this. all involve nested loops and/or recursion.

@jpadie: Thanks, but after much work I was able to resolve it with a small function like so:

function fn_combine ($items, $perms = array ()){
   if (empty ($items)){
       echo join(" ", $perms);
   } else {
       for ($i = count ($items)-1; $i >=0; --$i){
            $newitems = $item;
            $newperms = $perms; 
            list ($foo) = array_splice($newitems, $i, 1);
            array_unshift($newperms, foo);
            fn_combine ($newitems, $newperms);
         }
     }
}

Thanks bro.
