PHP access class inside another class

Question

So I have two classes like this:

class foo {
    /* code here */
}
$foo = new foo();
class bar {
    global $foo;
    public function bar () {
        echo $         


        

Answer 1

And if your only focus is the methods themselves as opposed to the instance of another class, you can use x extends y.

class foo {
  function fooMethod(){
    echo 'i am foo';
  }
}

class bar extends foo {
  function barMethod(){
    echo 'i am bar';
  }
}

$instance = new bar;
$instance->fooMethod();
