How can functions from one class access functions or values from another class in PHP?

To allow functions from one class to access functions or values from another class in PHP, you can use object-oriented programming techniques such as creating instances of the other class within the first class or passing instances of the other class as parameters to the functions. This allows for interaction between the classes and access to their methods and properties. 

class ClassA {
    public function doSomething(ClassB $classB) {
        // Access functions or values from ClassB
        $classB->someMethod();
        $value = $classB->someProperty;
    }
}

class ClassB {
    public function someMethod() {
        // Method logic
    }

    public $someProperty = 'value';
}

$classA = new ClassA();
$classB = new ClassB();

$classA->doSomething($classB);
