This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. Previous Comments: ------------------------------------------------------------------------ [2005-11-21 21:52:34] [EMAIL PROTECTED] I have a fix for this problem as well as speedup of the current code that handles unsigned ints on 32bit but I will push it after 5.1.0 is released because it's a bit too late in the release cycle. ------------------------------------------------------------------------ [2005-11-15 18:37:22] [EMAIL PROTECTED] I am taking care of this problem. Thanks! ------------------------------------------------------------------------ [2005-11-10 08:54:25] [EMAIL PROTECTED] Andrey, really REALLY big ints don't work yet! :) ------------------------------------------------------------------------ [2005-11-10 04:36:13] php at pjberkel dot com I compiled the latest CVS snapshot from the 5.1 branch (php5-200511100130) and can confirm that the problem has been fixed for 32bit unsigned INT values. However, I also did some further testing using the unsigned BIGINT data type (which contain 64bit integer values) and discovered the same problem exists for unsigned values larger than the maximum signed 64bit value: (9223372036854775807 < int <= 18446744073709551615) (BTW I'm using http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html as a reference page for MySQL numerical types.) Changing the following two lines in the original reproduce code fragment: $mysqli->query("CREATE TABLE temp (id BIGINT UNSIGNED NOT NULL)"); $mysqli->query("INSERT INTO temp (id) VALUES (9223372036854775807),(9223372036854775808),(18446744073709551614),(18446744073709551615)"); Expected result: ---------------- string(19) "9223372036854775807" string(19) "9223372036854775808" string(20) "18446744073709551614" string(20) "18446744073709551615" Actual result: -------------- string(19) "9223372036854775807" string(20) "-9223372036854775808" int(-2) int(-1) I don't want to push the envelope too much on this as I guess it would be extremely rare for anyone to encounter this bug, but if there is a quick, easy solution then it's probably a good idea to fix the unsigned BIGINT problem too. Any plans to backport this to the 5.0.x branch? Thanks ------------------------------------------------------------------------ [2005-11-09 14:44:17] [EMAIL PROTECTED] Hi, this has been addressed in the 5.1 branch. So far HEAD (6.0) is not patched, neither 5.0. Fixed is that a value from PS if the platform is 32bit and the type is int(11) unsigned and if the value is > MAX_INT a string will be returned. If the value <= MAX_INT an int will be returned. I know it's not nice to have different types but these are the limitations of PHP. In year or 2 most servers will run on 64bit :) Regarding the types returned. mysqli_query() always returns strings which is not that quite efficient in terms of memory consumption but the underlying libmysql functions return strings. It's matter of choice whether this can be optimized (by using more CPU cycles to reduce memory consumption). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
