Hello list, I have a little question with PHP's internal working. I've managed to reduce the test to the following lines:
$globalVariable = 'i am a global variable';
function testFunction() {
global $globalVariable;
unset($globalVariable);
}
testFunction();
if(isset($globalVariable)) {
var_dump('global variable IS set');
} else {
var_dump('global variable is NOT set');
}
When executing the above test, you will get printed that the global variable is set, despite unsetting it in the function. Is it really the intention to unset a global variable inside a function locally or have I just happen to found a little bug?

If it is expected behavior, is there any documentation on why this is done this way?
Greetings and thanks.
