note 84260 added to function.get-object-vars

If you're using the SPL ArrayObject class (or similar, or the ArrayAccess interface), you may have noticed that it's difficult to loop through an object's properties. get_object_vars does not return the properties of an ArrayObject. The only workaround I can see is to use get_class_vars. <?php $obj = new ArrayObject(); $obj->foo = "bar"; $obj[] = "1"; $obj[] = "2"; foreach($obj as $key => $value) { // will iterate over the array, iterating over "1" and "2", but ignoring $obj->foo } var_dump($obj); // dumps the array values, ignores $obj->foo $a = get_object_vars($obj); // returns an empty array class Fart extends ArrayObject { public $foo = "bar"; } $obj = new Fart(); $a = get_object_vars($obj); // return an empty array $a = get_class_vars(get_class($obj)); // returns array("foo"=>"bar"), Yay! /* The above works with subclasses as well */ class Toot extends Fart { public $weeble = "wobble"; } $a = get_class_vars(get_class($obj)); // returns array("weeble" => "wobble", "foo"=>"bar"), Yay again! ?> So, to iterate over the properties of an ArrayObject, and not the array values: <?php $obj = new Toot(); // which is a subclass of ArrayObject $props = get_class_vars(get_class($obj)); foreach($props as $prop => $defaultValue) { $value = $obj->$prop; // now you have the property name and its value } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 70.128.47.139 ---- Manual Page -- http://www.php.net/manual/en/function.get-object-vars.php Edit -- https://master.php.net/note/edit/84260 Del: integrated -- https://master.php.net/note/delete/84260/integrated Del: useless -- https://master.php.net/note/delete/84260/useless Del: bad code -- https://master.php.net/note/delete/84260/bad+code Del: spam -- https://master.php.net/note/delete/84260/spam Del: non-english -- https://master.php.net/note/delete/84260/non-english Del: in docs -- https://master.php.net/note/delete/84260/in+docs Del: other reasons-- https://master.php.net/note/delete/84260 Reject -- https://master.php.net/note/reject/84260 Search -- https://master.php.net/manage/user-notes.php
