Accessing a function from within a function in php?

Question

How does scope work for functions in PHP? Can I use function A (defined outside function B) from within function B?

You could have made a simple test and find out by yourself... — Catalin

You are right, but I had a problem with this in a website but the culprit was a different problem. Anyway even if its is an "easy"question, I am sure it will be useful for somebody googling it, so no need to be so whiny. — agente_secreto

All functions and classes in PHP have the global scope - they can be called outside a function even if they were defined inside and vice versa.

So yes, you can.

Yes, you can do it like this:

function A()
{
  ...
}

function B()
{
  A();
}

B();

Variable scope if for variables.

There is no "scope" for functions... except when using namespaces.

Quoting the User-defined functions section of the manual :

All functions and classes in PHP have the global scope - they can be called outside a function even if they were defined inside and vice versa.
