[SOLVED] Scope of a function in PHP

[dhruvasagar]

I am a beginner in PHP programming so I apologize if this is a stupid question or something that has already been answered. My question is what is the scope of a function defined in a php file?

If I want to call a function I defined in another file, do I need to do something like include that PHP file in this new PHP file or will it be just accessible? Though personally I think we'll need to include it of course...

 

The problem in searching is that when I do search for this, I end up reading excerpts for function scope, i.e. scope of variables etc which are declared within a function, that's not what I am looking for, I want to know the scope of these declared functions...

 

I have programming knowledge as well as experience in c/c++/java/VB/VC++/C#/ASP/Advanced Java/.NET etc...hence i understand most of the concepts of OOP as well as general programming.

this is a basic setup of using an external function

 

<?php
include "common.php";
hello();
bye("madtechie");
?>

 

common.php

<?php
function hello()
{
echo "hello world<br>";
}

funtion bye($name)
{
echo "bye bye $name";
}
?>

I thought so, I just wasn't able to confirm by searching because i wasn't getting proper results.

Thanks a lot
