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

Make it a member of bar. Try to never use globals.

class bar {
    private $foo;

    public function __construct($foo) { $this->foo = $foo; }

    public function barMethod() {
        echo $this->foo->something();
    }
}
