PHP arrays - simple query

Question

Ok I know this is simple, in fact damn simple, I did this in the last project about a week ago, but I don't know why it has skipped off my head.

Input:

$word = "stack";

What I want to do is:

$array = array("s", "t", "a", "c", "k");

Any help will be appreciated!

Answer 1

str_split();

Answer 2

var_dump(str_split("abc"));

Answer 3

Your question isn't too clear, but I suspect you want to turn your string into an array. You don't have to, actually. You can just access $word as if it were an array:

$word = 'stack';
for ($i=0, $m = strlen($word); $i < $m; $i++)
    echo $word[$i], "\n";
