<?php $object = (object) array("123.5"=>"456"); foreach ($object as $key => $value) { echo $key . ' => ' . $value,"\n"; } $object = (object) array(123.5=>"456"); foreach ($object as $key => $value) { echo $key . ' => ' . $value,"\n"; } // neither array key is suitable for identifier of object property b/c identifiers cannot start with a number. Why?
