Is it possible to have a function with 2 returns like this:
function test($testvar)
{
// do something
return $var1;
return $var2;
}
If so, how would I be able to get each return separately?

There is no way of returning 2 variables. Although, you can propagate an array and return it; create a conditional to return a dynamic variable, etc.
For instance, this function would return $var2
function wtf($blahblah = true) {
$var1 = "ONe";
$var2 = "tWo";
if($blahblah === true) {
return $var2;
}
return $var1;
}
In application:
echo wtf();
//would echo: tWo
echo wtf("not true, this is false");
//would echo: ONe
If you wanted them both, you could modify the function a bit
function wtf($blahblah = true) {
$var1 = "ONe";
$var2 = "tWo";
if($blahblah === true) {
return $var2;
}
if($blahblah == "both") {
return array($var1, $var2);
}
return $var1;
}
echo wtf("both")[0]
//would echo: ONe
echo wtf("both")[1]
//would echo: tWo
list($first, $second) = wtf("both")
// value of $first would be $var1, value of $second would be $var2
