<?php // PHP program to illustrate the // ArrayObject::setFlags() function // Declare an array and convert // it into array object $arrObject = new ArrayObject(
array ( 'Geeks' , 'for' , 'Geeks' )
); // Use ArrayObject::getFlags() function // to get the behavior of flags $flag = $arrObject ->getFlags();

"c" => "GeeksforGeeks"
); // Create array object $arrObject = new ArrayObject( $arr );
// Use ArrayObject::getFlags() function // to get the behavior of flags $flag = $arrObject ->getFlags();
