Will a function in an if statement only be read if the statement is true?

If I put a function into an if statement is this an effective way to 'declare only if not yet declared'? I read on another thread that functions nested inside others worked the same as non-nested (not sure this applies here). Will my function always execute or only when if is true?

  if(!function_exists('myFunction')){
    //Add myFunction just in case it wasn't declared previously
    function myFunction() { 
    // do something
    }  
    myFunction();
  }
  else {
    myFunction();
  }

Alternatively, is there a better way to do this, being that the function may or may not be previously declared in a parent file?

place function myFunction(){} outside of the if statement if you plan to call it elsewhere (like in your else statement)
