从另一个函数内的switch函数返回变量

Question

I have this basic function getdetails(), I simplified the code that way its easy to understand what I need. I would like to be able to echo (or use) the value of title or lname outside of the function getdetails. Any help would be greatly appreciated

function getdetails ($var){
    $title = "Hello World";
    $lname = "John Doe";
    switch ($var)
    {
        case "title":return $title; break;
        case "lastname":return $lname; break;
    }
}

echo "title is: ".$title;

Answer 1

getdetails returns a value. To get that value, assign it to a variable like so:

$title = getdetails('title');

Then you can use it as any other variable

echo "title is: " . $title;
