How can version information in PHP classes be accessed and utilized effectively, especially in scenarios without external dependencies?

To access and utilize version information in PHP classes effectively, you can define a constant within the class to store the version number. This allows easy access to the version information within the class itself without relying on external dependencies. 

class MyClass {
    const VERSION = '1.0.0';

    public function getVersion() {
        return self::VERSION;
    }
}

$myClass = new MyClass();
echo $myClass->getVersion(); // Output: 1.0.0
