is_null Previous Comments: ------------------------------------------------------------------------ [2009-05-22 18:38:30] clement dot hallet at af83 dot com Sorry for the bad status :) Please note that because of : $a = NULL; isset($a) -> FALSE is_null($b) -> TRUE (a notice happend) It's impossible to test if a variable is _set_ to NULL :/ ------------------------------------------------------------------------ [2009-05-22 18:26:18] paj...@php.net no bug > bogus :) ------------------------------------------------------------------------ [2009-05-22 18:23:11] clement dot hallet at af83 dot com That bug report is void. Have seen http://fr3.php.net/manual/en/function.isset.php Maybe a change betweens versions ? ------------------------------------------------------------------------ [2009-05-22 18:14:32] clement dot hallet at af83 dot com Description: ------------ Hi, A call to the 'isset' function with a variable set to NULL returns FALSE. As seen on a previous report bug (http://bugs.php.net/bug.php?id=6076), the return value should be TRUE. Reproduce code: --------------- $a = NULL; var_dump(isset($a)); Expected result: ---------------- the return of isset($a) should be TRUE. Actual result: -------------- isset($a) returns FALSE ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48364&edit=1
