Description: ------------ It seems that ArrayObject should implement ArrayAccess given that it already implements Traversable. For me to know if a given variable can be accessed with the [] operator, I need to do: if (is_array($obj) || $obj instanceof ArrayAccess || $obj instanceof ArrayObject) { } Reproduce code: --------------- function array_check($obj) { if (is_array($obj)) { print "Is an array()<br />\n"; } if ($obj instanceof ArrayAccess) { print "Implements ArrayAccess<br />\n"; } if ($obj instanceof ArrayObject) { print "Is an instance of ArrayObject<br />\n"; } } array_check(new ArrayObject(array())); Expected result: ---------------- Implements ArrayAccess Is an instance of ArrayObject Actual result: -------------- Is an instance of ArrayObject -- Edit bug report at http://bugs.php.net/?id=28099&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28099&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28099&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28099&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28099&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28099&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28099&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28099&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28099&r=support Expected behavior: http://bugs.php.net/fix.php?id=28099&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28099&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28099&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28099&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28099&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28099&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28099&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28099&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28099&r=float
