Shouldn't it produce the same result? Reproduce code: --------------- $arr = array(); echo( is_null( $arr ) ? "is_null: NULL\n" : "is_null: NOT NULL\n" ); echo( (null == $arr) ? "null: NULL\n" : "null: NOT NULL\n" ); Expected result: ---------------- is_not: NOT NULL null: NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25292&edit=1
