From: Operating system: PHP version: 5.3.10 Package: Documentation problem Bug Type: Documentation Problem Bug description:clone operator precedence is wrong Description: ------------ --- From manual page: http://www.php.net/language.operators.precedence --- According to the Operator Precedence table, the clone operator has higher precedence than [. This would mean clone $arraylike[0] is evaluated as ( clone $arraylike )[0], but it seems that the implementation does clone ( $arraylike[0] ). I think this is probably correct behavior, so I conclude the documentation is incorrect. Test script: --------------- $a = array( new stdClass() ); clone $a[0]; Expected result: ---------------- in this case, some type error at runtime since you can't clone an array Actual result: -------------- the object at offset 0 is cloned -- Edit bug report at https://bugs.php.net/bug.php?id=61513&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61513&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61513&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61513&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61513&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61513&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61513&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61513&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61513&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61513&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61513&r=support Expected behavior: https://bugs.php.net/fix.php?id=61513&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61513&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61513&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61513&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61513&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61513&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61513&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61513&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61513&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61513&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61513&r=mysqlcfg
