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.

Answer 1

In order to get the values of each variable, you need to treat the function as you would an array:

function data() {
    $a = "abc";
    $b = "def";
    $c = "ghi";
    return array($a, $b, $c);
}

// Assign a variable to the array; 
// I selected $dataArray (could be any name).

$dataArray = data();
list($a, $b, $c) = $dataArray;
echo $a . " ". $b . " " . $c;

//if you just need 1 variable out of 3;
list(, $b, ) = $dataArray;
echo $b;
