Fatal error: Cannot redeclare...

[Just Another Victim of the Ambient Morality]

I have a peculiar bug in my PHP code. It looks something like this:

Fatal error: Cannot redeclare func_name() (previously declared in
script.php:57) in script.php on line 57

I've done a search and determined that "func_name" really is unique.
Besides, how is this even possible? It was previously declared on the
same line it's declared?
Any help is appreciated. Thank you!

Are you accidentally including the same file more than once?

Thank you for the quick reply!
I don't think I'm including it more than once.
Actually, what I'm doing is this:

function func($input)
{
function func_name($e)
{
return $e + 1;
}

return array_map('func _name', $input);
}

This appears to be what's causing the error.
I would have guessed that it was okay but, apparently, defining
"func_name" in "func" decorates it, somehow. However, I read some
documentation saying that all function names have global scope, regardless
of where it was defined.
So, is this possibly a bug?
Thank you...

func_name() is declared when you run func(). That means that if you run
func() more than once you'll declare func_name() more than once, what is
not allowed.

Just move func_name() outside func(), I see no reason to declare it inside.

It looks like you've done lots of JavaScript stuff. Sorry, PHP is way
different.

So, is this possibly a bug?

Yes, it's a bug in your code ;-)

function func($input) {
if (!function_exis ts('func_name') ) {
function func_name($e){{
return $e + 1;
}
}
return array_map('func _name', $input);
}

Try this!
