PHP - Make multi-dimensional associative array from a delimited string

Question

Can you turn this string:

\"package.deal.category\"

Into an array like this:

$array[\'package\'][\'deal\'][\'category\']
         


        

Answer 1

What have you tried? The absolute answer to this is very easy:

$keys = explode('.', $string);
$array = array();
$arr = &$array;
foreach ($keys as $key) {
   $arr[$key] = array();
   $arr = &$arr[$key];
}
unset($arr);

...but why would this be useful to you?
