php - How to cast variable to array

Question

I have a variable $v that can be either single string or array of strings
and I have a code:

$a = array();
if (is_array($v)) {
    $a = $v;
} else {
    $a[] = $v;
}

How it can be done in more elegant way? (in other words, how to cast a variable to array)

Answer 1

You can cast a variable to an array by using:

    $var = (array)$arr;
