php - How to access the elements of a function's return array?

Question

I need to return multiple values from a function, therefore I have added them to an array and returned the array.

<?
function data(){
    $a = "abc";
    $b = "def";
    $c = "ghi";

    return array($a, $b, $c);
}
?>

How can I receive the values of $a, $b, $c by calling the above function?

Answer 1

You can add array keys to your return values and then use these keys to print the array values, as shown here:

function data() {
    $out['a'] = "abc";
    $out['b'] = "def";
    $out['c'] = "ghi";
    return $out;
}

$data = data();
echo $data['a'];
echo $data['b'];
echo $data['c'];
