Req #63954 [NEW]: Parser should recognize objects within parenthesis

From: php at kfee-programming dot com Operating system: Debian GNU/Linux 6.0 PHP version: 5.3.20 Package: Compile Failure Bug Type: Feature/Change Request Bug description:Parser should recognize objects within parenthesis Description: ------------ Placing any object within parentheses and attempting to access members of that object causes the parser to fail with an error. This makes chaining difficult, particularly with clones. One would expect that parenthesis should have no effect on the identity of the variable or expression they are surrounding, but this failure of the parser causes a change in identity to not-an-object. This was reported as a bug #30533, but was declared NAB with no additional reasoning. This is thus a change request. Test script: --------------- <?php $Now = new \DateTime(); $OneSecAgo = (clone $Now)->sub(new \DateInterval("PT1S")); //Or $OneSecAgo = clone($Now)->sub(new \DateInterval("PT1S")); //Neither work. echo $Now->format("c") , "\n" , $OneSecAgo->format("c"); Expected result: ---------------- 2013-01-09T17:01:35-08:00 2013-01-09T17:01:34-08:00 Actual result: -------------- [Wed Jan 09 17:01:35 2013] [error] [client *.*.*.*] PHP Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /var/www/test.php on line 3 -- Edit bug report at https://bugs.php.net/bug.php?id=63954&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63954&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63954&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63954&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63954&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63954&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63954&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63954&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63954&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63954&r=support Expected behavior: https://bugs.php.net/fix.php?id=63954&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63954&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63954&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63954&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63954&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63954&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63954&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63954&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63954&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63954&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63954&r=mysqlcfg
