Objects - Static properties and methods
The issue: Implementing singleton pattern
property = microtime();
}
public static function getInstance() {
if (!isset(self::$instance)) {
self::$instance = new Singleton();
}
return self::$instance;
}
}
var_dump( Singleton::getInstance() );
var_dump( Singleton::getInstance() );
?>]]>
PHP 4 could only simulate a singleton with global variables.
Static properties may be accessed without a class instance.
