Access object instances created by functions in PHP

I am just getting into OOP PHP but have got a little stuck.

Basically i want to create a function to create the objects, the issue is i can't then access the objects outside of the function:

$website0 = new website(0,'test','NameTest');
echo $website0 ->getProperty('name');

This works. However:

createWebsitesFromDatabase();
echo $website0 ->getProperty('name');

function createWebsitesFromDatabase() {
    $website0 = new website (0,'test','NameTest');
}

does not work. Any ideas?

You have to assign the created object to a variable outside the function by using a return value, that's better than using global in most cases.

<?php
   function createWebsitesFromDatabase(){
       $insideVar = new website(0, 'test', 'NameTest');
       return $insideVar;
   }

   $website0 = createWebsitesFromDatabase();
   echo $website0->getProperty('name');
?>

do this:

function createWebsitesFromDatabase() {
global $website0;
$website0 = new website (0,'test','NameTest');
}

function createWebsitesFromDatabase() {
   global $website0; // here is the trick
   $website0 = new website (0,'test','NameTest');
}

createWebsitesFromDatabase();    
echo $website0 ->getProperty('name');
