From: lindsay.marshall@ncl.ac.uk Operating system: redahat 7.2 PHP version: 4.2.0 PHP Bug Type: Math related Bug description: Bitwise & does not give expected results I have a piece of code that effectively does this : $r->f = 8191; $c->m = 7; $r->f & $c->m returns 0!! The above code works fine when tested standalone, but the equivalent code in my program generates 0. I can write ; echo $r->status.' '.$current->mask.' '.($r->status&$current->mask); and the output I get is 8191 7 0 If I write : $a1=7;$a2=8191; echo $r->status.' '.$current->mask.' '.($a1&$a2); I get 8191 7 7 Something is getting confused somewhere!! -- Edit bug report at http://bugs.php.net/?id=17116&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17116&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17116&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17116&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17116&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17116&r=support Expected behavior: http://bugs.php.net/fix.php?id=17116&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17116&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17116&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17116&r=globals
