Access class property from outside of class

Question

Suppose I had the following class:

class MyClass {
    public function Talk() {
        $Say = "Something";
        return $Say;
    }
}

I then started an instance of the class:

$Inst = new MyClass();

How can I now call $Say outside MyClass hence, for example, echo it on the document? For example, having something like:

$Said = "He" . $Say

Answer 1

I strongly recommend you read through http://php.net/manual/en/language.oop5.php. It will teach you the fundamentals of OOP in PHP.

In your example, $Say is just another variable declared within Talk()'s scope. It is not a class property.

To make it a class property:

class MyClass {
    public $say = 'Something';

    public function Talk() {
        return $this->say;
    }
}

$inst = new MyClass();
$said = 'He ' . $inst->say;

That defeats the purpose of Talk() however.
The last line ought to be $said = 'He '. $inst->Talk();

Answer 2

$say is not a class property. If it was, you would define your class like this:

class MyClass {
    public $say;      
}

It is instead a local variable of the function Talk(). If you want to access it the way that you have the class defined, you would do:

$instance = new MyClass();
$instance->Talk();
