From: Operating system: win32 PHP version: Irrelevant Package: Strings related Bug Type: Bug Bug description:Decrementing character variables does not work as expected
Description: ------------ In the documentation (http://www.php.net/manual/en/language.operators.increment.php), "Example #1 Arithmetic Operations on Character Variables" shows how strings can be incremented. You would expect this to work the opposite way, too -- however, it doesn't. See the modified code from Example #1 attached. Test script: --------------- $i = 'W'; for ($n=0; $n<6; $n++) { echo --$i . "\n"; } Expected result: ---------------- V U T S R Q Actual result: -------------- W W W W W W -- Edit bug report at http://bugs.php.net/bug.php?id=54635&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54635&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54635&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54635&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54635&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54635&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54635&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54635&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54635&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54635&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54635&r=support Expected behavior: http://bugs.php.net/fix.php?id=54635&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54635&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54635&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54635&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54635&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54635&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54635&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54635&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54635&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54635&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54635&r=mysqlcfg
