// it into array object 
$arrObject = new ArrayObject( 
    array('Geeks', 'for', 'Geeks') 
);

// to get the behavior of flags 
$flag = $arrObject->getFlags();

// Set a new flags 
$arrObject->setFlags(ArrayObject::STD_PROP_LIST); 
  
// Use ArrayObject::getFlags() function 
// to get the behavior of flags 
$flag = $arrObject->getFlags();
