From: Operating system: Win 7 PHP version: 5.3.2 Package: MySQLi related Bug Type: Bug Bug description:mysqli_result::fetch_all returns null, not an empty array
Description: ------------ The documentation says that mysqli_result::fetch_all - "fetches all result rows and returns the result set as an associative array, a numeric array, or both" - "Returns an array of associative or numeric arrays holding result rows" (though the return type is "mixed"). As far as I can tell, fetch_all returns NULL when there are no rows (ie, ->num_rows==0). Filed as a bug and not a documentation problem because it'd be nice to always get an array back. Test script: --------------- // Requires that mysqlnd be loaded, of course // $mysqli = new mysqli(...) $result = $mysqli->query("SELECT 1 LIMIT 0"); var_dump($result->fetch_all()); Expected result: ---------------- array(0) { } Actual result: -------------- NULL -- Edit bug report at http://bugs.php.net/bug.php?id=52115&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52115&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52115&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52115&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52115&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52115&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52115&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52115&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52115&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52115&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52115&r=support Expected behavior: http://bugs.php.net/fix.php?id=52115&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52115&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52115&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52115&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52115&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52115&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52115&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52115&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52115&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52115&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52115&r=mysqlcfg
