here your doing exactly what you first asked if you could do
and were told you couldn't (not exactly like that anyhow)
($array.$suffix) will never be an array
> $suffix .= "['".$key."']";
this $suffix 'path' is being created in a way that
is not compatible with getVal(). the second arg
to getVal() can either be an array where the values
are the keys to 'dig' in with or a comman delimited
string containg the key names ... e.g:
$path1 = array('key1','key2','key3');
$path2 = 'key1,key2,key3';
$path1 and $path2 will give the same result.

getVal() will only ever return NULL

array_count_values() might interest you.
