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

Your function is:

function data(){

$a = "abc";
$b = "def";
$c = "ghi";

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

It returns an array where position 0 is $a, position 1 is $b and position 2 is $c. You can therefore access $a by doing just this:

data()[0]

If you do $myvar = data()[0] and print $myvar, you will get "abc", which was the value assigned to $a inside the function.
