Return multiple values by reference

I am trying to return multiple variables in a function to another php page.

I looked at other sources but I can't get it to work. What am I doing wrong here?

function byRef($value1, &$value2, &$value3){

    global $value1, $value2, $value3;

    string.$value1 = "Hello";
    string.$value2 = "World";
    string.$value3 = " ";

    string.$value3 .= $value1 . $value2 ;

}

byRef($value1, $value2, $value3);

echo $value3;

Help is appreciated

Don't use global, it imports the variables that are not in the function.

Don't use that string. something either. I don't know what it is or if it exists, but don't use it.

<?php

$value1 = 'not hello';

function byRef($value1, &$value2, &$value3){

    $value1 = "Hello";
    $value2 = "World";
    $value3 = " ";

    $value3 .= $value1 . $value2 ;

}

byRef($value1, $value2, $value3);

echo $value3;
