Can you illustrate this with a (small) code example on how you would like to see it? I think you also want to have a look at php.net/function_exists .

Derick

sure, ok, well here is an example. Lets assume that this is a form submitted and the action was PHP_SELF

ok

if($_POST['sent'])
{

function do_something()
{
//do stuff
}

echo("I need to use my function");
do_something();

}
else
{
echo("wait, I also need it and the author accidently put it inside that if!");
do_something();
}

like that.
If I were to redeclare it in the else, then it tells me that i have defuned it twice, so it obviously sees the function is defined, but if I call it I get an error, now this can be easily solved by moving the declaration, but I just think it would be helpful if it accidently happened, it took me forever to figure out what I accidently did

I don't understand the request.
