#33622 [NEW]: $i++ is not $i+1

From: meh at v-cm dot net Operating system: Windows XP PHP version: 4.3.11 PHP Bug Type: Scripting Engine problem Bug description: $i++ is not $i+1 Description: ------------ The operators ++ and -- don't increment/decrement boolean values. This behaviour could be extremly annoying when you have something like: $key = array_search($thekey, array_keys($thearray)); for($i=$key; $x<count($thearray); $i++) echo "foo"; Workaround: $key = array_search($thekey, array_keys($thearray)); if($key==false) $key=0; for($i=$key; $x<count($thearray); $i++) echo "foo"; If this behaviour is intended, then it should at least be documented that ++,-- doens't convert boolean values. Reproduce code: --------------- // Works $x = false; echo $x+1; // Outputs 1 // Doesn't work $x= false; $x++; echo $x; // Outputs nothing Expected result: ---------------- 11 Actual result: -------------- 1 -- Edit bug report at http://bugs.php.net/?id=33622&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33622&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33622&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33622&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33622&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33622&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33622&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33622&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33622&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33622&r=support Expected behavior: http://bugs.php.net/fix.php?id=33622&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33622&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33622&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33622&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33622&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33622&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33622&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33622&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33622&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33622&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33622&r=mysqlcfg
