"\n"; return serialize( $tmp ); } } $n = array(); $n[0] = new test('tmp1'); $n[1] = new test('tmp2'); print_r( unserialize( serialize( $n ) ) ); Expected result: ---------------- O:8:"stdClass":1:{s:1:"a";s:4:"tmp1";} O:8:"stdClass":1:{s:1:"a";s:4:"tmp2";} Actual result: -------------- O:8:"stdClass":1:{s:1:"a";s:4:"tmp1";} r:3; -- Edit bug report at https://bugs.php.net/bug.php?id=66085&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66085&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66085&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66085&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66085&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66085&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66085&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66085&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66085&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66085&r=support Expected behavior: https://bugs.php.net/fix.php?id=66085&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66085&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66085&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66085&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66085&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66085&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66085&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66085&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66085&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66085&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66085&r=mysqlcfg
