Question

Is there a way to achieve the following in PHP, or is it simply not allowed? (See commented line below)

function outside() {
    $variable = 'some value';
    inside();
}

function inside() {
    // is it possible to access $variable here without passing it as an argument?
}

Answer 1

Its not possible. If $variable is a global variable you could have access it by global keyword. But this is in a function. So you can not access it.

It can be achieved by setting a global variable by$GLOBALS array though. But again, you are utilizing the global context.

function outside() {
    $GLOBALS['variable'] = 'some value';
    inside();
}

function inside() {
        global $variable;
        echo $variable;
}
