Includes and Functions calls

[Sycoloco]

I just want to confirm something as my understanding has been shaken by a test I did on another server that I expected something to work and it didn't. Please see question in code below.\[code\]<?phpfunction xyz(){} include("test.php");/** A function in the above include checks if the function abc function_exists(). * Will it return a true? What about for xyz?*/function abc(){}?>\[/code\]Thanks all
