From: Operating system: irr PHP version: Irrelevant Package: Class/Object related Bug Type: Bug Bug description:request for interface hashCode (Identifiable) Description: ------------ i, i hope to see something like this in future php releases interface Identifiable { public function /*string*/ hashCode(); } class Test implements Identifiable { public function hashCode(){return spl_object_hash($this);} } method hashCode() should be called in these contexts: $myarr[new Test()] = "test"; $myarrobj->{new Test()} = "test"; and manually inside: function method(Identifiable $instance){}; the hash should be obtained by calling $obj->hashCode() if it is Identifiable or $obj->scalarValue() if it implements ScalarAccess $obj->__toString() if it has method __toString or, finally throw an error what do you think about this? thank you -- Edit bug report at http://bugs.php.net/bug.php?id=52528&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52528&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52528&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52528&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52528&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52528&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52528&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52528&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52528&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52528&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52528&r=support Expected behavior: http://bugs.php.net/fix.php?id=52528&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52528&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52528&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52528&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52528&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52528&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52528&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52528&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52528&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52528&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52528&r=mysqlcfg
