include a page lets say the function is GetPage and the variable is ID

<?php
require('page.php');

$id = ($_GET['id']);

if($id != '') {
  getpage($id);
}
?>

now when you make the function

<?php
function getpage($id){
if ($id = ''){
//// Do something
}
else {
}
}
?>

In PHP it's not available to get only a little part of a file.

Maybe this is a ability to use only little parts of a file:

I have a class that calls "utilities". This I am using in my projects.

In my index.php

include("class.utilities.php")
$utilities = new utilities();

The file class.utilities.php

class utilities {
    function __construct() {

    }
    public function thisIsTheFunction($a,$b)
    {
        $c = $a + $b;
        return $c;
    }
}

And then i can use the function

echo $utilities->thisIsTheFunction(3,4);

The short answer is: no, you can't.

The long answers is: yes, if you use OOP.

Split your functions into different files. Say you are making a game with a hero:

Walk.php

function walk($distance,speed){
   //walk code
}

Die.php

function die(){
    //game over
}

Hero.php

include 'Walk.php';
include 'Die.php';

class Hero(){
    //hero that can walk & can die
}

You may have other functions like makeWorld() that hero.php doesn't need, so you don't need to include it. This question has been asked a few times before: here & here.

One of the possible methods outlined before is through autoloading, which basically saves you from having to write a long list of includes at the top of each file.
