php static in if statement

I have a construction like this in my config file:

<?php
if (true) {
    $nonstatic = 1;
    static $config = 1;
}
else {
    $nonstatic = 2;
    static $config = 2;
}

echo $nonstatic;
echo $config;
?>

So why the $config contains 2 if this part of the statement is false and $nonstatic contains 1? Is it开发者_如何学Python a bug?

I suppose this chunk is being included from a function.

Initialisations of static variables are resolved at compile-time, and if the interpreter finds multiple initialisations, it simply takes the bottom one.
