#49772 [NEW]: Cast operators marked as non-associative

From: mjomble at gmail dot com Operating system: Windows PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Cast operators marked as non-associative Description: ------------ The operator precedence page (language.operators.precedence.php) lists the following operators as non-associative: ~ - (int) (float) (string) (array) (object) (bool) @ However, all of these seem to behave like right-associative operators. Examples: - - 3 evaluates like -(-3)) = 3 ~ ~ 3 evaluates like ~(~3)) = 3 - - - 3 evaluates like -(-(-3))) = -3 ~ ~ ~ 3 evaluates like ~(~(~3))) = ~3 = -4 (int) (string) 3 evaluates to integer 3 (string) (int) 3 evaluates to string "3" It's even possible to use the @ operator more than once in front of a statement. The additional ones don't really do anything useful, but more importantly, they don't trigger any parse errors. -- Edit bug report at http://bugs.php.net/?id=49772&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49772&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49772&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49772&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49772&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49772&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49772&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49772&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49772&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49772&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49772&r=support Expected behavior: http://bugs.php.net/fix.php?id=49772&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49772&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49772&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49772&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49772&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49772&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49772&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49772&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49772&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49772&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49772&r=mysqlcfg
