calling object methods within a function

[Anon]

I'm having a problem calling a method from within a function. Here is some simplified code that recreates the problem:

<?

class base {
var $error;

function base() {
    $this->error = FALSE;
}
function error( $message ) {
    $this->error = TRUE;
    echo "There was an error: $message";
}

}

$base = new base;

$base->error( "This does not cause an error");

function test() {
$msg = "<b>Fatal Error:</b> Call to a member function on a non-object in following line";
$base->error( $msg );
}

test();

?>

Above I am declaring a class, instantiating it, and trying to access one of the methods from within a function. This results in the error message: "Call to a member function on a non-object". I CAN use the method outside of the function without a problem.

It DOES work if the line,

$obj_in_function = new base;

is inserted inside the function test(), so I know this is a scope issue, but I'm confused. Isn't the whole point of having a class is so I can reuse the methods as I need to?

I'm guessing I'm missing something simple here!

yea, is a scope issue.

you should declare `$base' var as global inside function.

function test() {
global $base;
...
}

Perfect! I can stop beating my head against the desk now, thanks to you.
