Description: ------------ I think the test script should be self explaining. Order is somewhat strange. Once it seems to be evaluated as $first = (+$i); // => 0 $second = ($i += 3); // => 3 $result = $first + $second; // => 3 and once as: $second = ($i += 3); // => 3 $first = ($i); // => 3 $result = $first + $second; // => 6 Test script: --------------- php > $i = 0; print (+ $i + ($i += 3))."\n"; 3 php > $i = 0; print ($i + ($i += 3))."\n"; 6 Expected result: ---------------- I'd expect that the parenthesis are only resolved if encountered and not first resolved, then the variable replaced by its value. -- Edit bug report at https://bugs.php.net/bug.php?id=63978&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63978&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63978&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63978&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63978&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63978&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63978&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63978&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63978&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63978&r=support Expected behavior: https://bugs.php.net/fix.php?id=63978&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63978&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63978&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63978&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63978&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63978&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63978&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63978&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63978&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63978&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63978&r=mysqlcfg
