2 questions about functions in PHP...

[diamonds]

Is thre a function in PHP that will return TRUE or FALSE if a function is set or not(without calling it!)?
(... if(isfunctionset(function)){}else{} ...)
I am just wondering...

and, Can you edit a global variable inside a function?

$my_not_your_global_var = '';

function change($add = ''){
$my_not_your_global_var .= @$add;
} 

I am having trouble with the second one mostly.

An awnser to these questions would make my life programing life a lot more easy!

On number one, I don't think so...

On number two, you need to define them as global variables:

<?PHP
function change($add = "test"){
    global $my_not_your_global_var;
    $my_not_your_global_var = $add;
}
change();
echo $my_not_your_global_var;
?>
