Req #54082 [NEW]: Cast array key objects to string

From: Operating system: Irrelevant PHP version: Irrelevant Package: Arrays related Bug Type: Feature/Change Request Bug description:Cast array key objects to string Description: ------------ Per http://www.php.net/manual/en/language.types.array.php, array keys can be integers or strings. If an object can be converted to a string representation (i.e. it has a __toString() method defined), it should be automatically cast to a string. Currently, an error is thrown instead. Current workaround is to manually cast to string when setting a key. Test script: --------------- class Foo { public function __toString() { return 'A'; } } $a = new Foo(); $b = array($a => 1); print_r($b); Expected result: ---------------- Array ( 'A' => 1 ) Actual result: -------------- PHP Warning: Illegal offset type [...] Array ( ) -- Edit bug report at http://bugs.php.net/bug.php?id=54082&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54082&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54082&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54082&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54082&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54082&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54082&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54082&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54082&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54082&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54082&r=support Expected behavior: http://bugs.php.net/fix.php?id=54082&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54082&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54082&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54082&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54082&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54082&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54082&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54082&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54082&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54082&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54082&r=mysqlcfg
