From: php at pjberkel dot com Operating system: RHEL 4 PHP version: 5CVS-2005-12-02 (snap) PHP Bug Type: MySQLi related Bug description: mysqli_stmt_fetch() incorrectly returning NULL
Description: ------------ This bug report is a follow-up to a previous bug: http://bugs.php.net/bug.php?id=35103 I tested the original reproduce code using the lastest stable snapshot available (php5.1-200512020130) and there appears to be another bug (or feature) introduced as a result of the fix to bug #35103. It appears as though $stmt->fetch() is returning NULL despite the fact that the result has been correcly bound to the variable (and this only seems to occur when the data is an unsigned int >= MAX_SIGNED_INT (as in bug #35103). I notice in the manual page that mysqli_stmt_fetch() returns NULL when "No more rows/data exists or data truncation occurred" so it would appear this is a bug. Can anybody confirm? (I'm using php5.1-200512020130 + mysql-5.0.16 on RHEL 4). Reproduce code: --------------- <?php $mysqli = new mysqli("host", "user", "pass", "db"); $mysqli->query("CREATE TABLE temp (id INT UNSIGNED NOT NULL)"); $mysqli->query("INSERT INTO temp (id) VALUES (3000000897),(3800001532),(3900002281),(3100059612)"); /* BEGIN EXAMPLE OF BUG */ $stmt = $mysqli->prepare("SELECT id FROM temp"); $stmt->execute(); $stmt->bind_result($id); while ($stmt->fetch()) { var_dump($id); } $stmt->close(); /* END EXAMPLE OF BUG */ $mysqli->query("DROP TABLE temp"); $mysqli->close(); ?> Expected result: ---------------- string(10) "3000000897" string(10) "3800001532" string(10) "3900002281" string(10) "3100059612" Actual result: -------------- [no output, while loop terminates immediately because $stmt->fetch() returns NULL] -- Edit bug report at http://bugs.php.net/?id=35517&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=35517&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=35517&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=35517&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=35517&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35517&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35517&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35517&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35517&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35517&r=support Expected behavior: http://bugs.php.net/fix.php?id=35517&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35517&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35517&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35517&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35517&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35517&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35517&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35517&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35517&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35517&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35517&r=mysqlcfg
