return statement

[simon_belak]

is there any way for a function to return something witch will stop the caller function (like a return)?

something like:

function fu()
{
...
checkForError();
...
}

function checkForError()
{
if (error)
{
return something witch will stop the caller function (like return return 0)
}
}

die() or exit() aren't suitable becouse they stop the whole script not just a function.

Why don't you just test for the return of a 0 in the calling function and if that is what you got back imediately return from that function a 0?

Sorry I should have included this example:

function fu()
{
...
if !(checkForError()) { return 0; }
...
}

function checkForError()
{
if (error)
{
return 0;}
}

[Anon]

function fu()
{
...
if (checkForError()) break;
...
}

function checkForError()
{
if (error)
{
return true; //return true indicates error
}
}

im assuming there is a look inside of fu() and thats what you want to break out of.

thanks i am aware of that solution.
But i am writing an error handleing class and i want to integrate its functions into my projects as much as possible, so i am looking for a neater solution.

function fu()
{
...
eval(checkForError());
...
}

function checkForError()
{
if (error)
{
return "return false;";
}
}
