I want to take an array and get the soundex() for each element in that array
and return the results into another array. Is there an clean way to do
this?
$color = array("blue", "green", "orange", "purple", "red", "yellow");
function sound(&$word){
$word = soundex($word);
}
array_walk($color, 'sound');
print join(" ", $color);
This will print out the array $color, which is now changed to soundex, i.e.
the original array (up top) has changed--which I don't want. How can I
generate a separate array $colorsoundex?
Thank you.
