From: mturner at cc dot umanitoba dot ca Operating system: linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Operator Pecedence
Description: ------------ According to the operator precdence docs, the modulus operator has precedence over the equals operator. But that is not in fact how it works, as a recent thread on the php general list has shown. Reproduce code: --------------- $s= 5; $d = 2; $result = ($s % $d=3); echo "3 incorrectly assigned to \$d: \$d=$d\n"; echo "result of mod = $result\n"; //$result here is 2: 5 % 3 Expected result: ---------------- This should give an error, instead it assigns 3 to $d and gives a result of 2. A parallel bug was reported with respect to the ! and the = operators in bug #17180, which resulted in a statement at the end of the operator precedence document which allows for an exception to the rule. Either the operator precedence rules should be respected or a general inquiry should be made into how php handles = and a general statement about it should be appended to the operator precedence docs. These exceptions to the operator precedence rules are not allowd in Perl. -- Edit bug report at http://bugs.php.net/?id=40820&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40820&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40820&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40820&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40820&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40820&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40820&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40820&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40820&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40820&r=support Expected behavior: http://bugs.php.net/fix.php?id=40820&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40820&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40820&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40820&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40820&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40820&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40820&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40820&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40820&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40820&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40820&r=mysqlcfg
