}

echo "$title";
?> 

echo can not shows anythings. why? how i can return $title to out of function?

[jpmoriarty]

either define your variable as a global one:

function title()
{
    global $title;
    $title = "this is a test";
}

title();
echo $title;

or return it at the end of the function:

function title()
{
    $title = "this is a test"
    return $title;
}

echo title();

it's all to do with scope
