From: jpokotilow at tuneteller dot com Operating system: Mac OS X 10.4.8 PHP version: 5.2.0 PHP Bug Type: PDO related Bug description: Can't iterate over a PDOStatement object using foreach()
Description: ------------ I invoke PDO::query() twice, with two different valid SQL queries from within a class method. (Note: I make sure to invoke fetchAll() on the PDOStatement object returned by the first invocation before invoking PDO::query() a second time. Update: I just found out that if I set the first PDOStatement object to NULL, everything works as intended. HOWEVER, invoking fetchAll() should suffice, should it not?) I return the PDOStatement object generated by the second PDO::query() invocation. I'm unable to iterate over the object with a foreach() construct even though there ought to be results. Invoking fetchAll() on the object returns an empty array. If I set the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute to true, I don't have this problem, but I'm pretty sure I shouldn't have it either way. Reproduce code: --------------- http://pastebin.com/825493 Expected result: ---------------- I expect to be able to iterate over rows associated with $broken_iterable_results ... or I would expect for $broken_iterable_results->fetchAll() to return rows associated with the PDOStatement object. At the very least, I expect for some error to be generated if I'm doing anything wrong. Note: With PDO::ERRMODE_EXCEPTION set to true, there is an exception thrown. Actual result: -------------- Iterating over $broken_iterable_results results does nothing. Invoking $broken_iterable_results->fetchAll() returns an empty array. -- Edit bug report at http://bugs.php.net/?id=39527&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39527&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39527&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39527&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39527&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39527&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39527&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39527&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39527&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39527&r=support Expected behavior: http://bugs.php.net/fix.php?id=39527&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39527&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39527&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39527&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39527&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39527&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39527&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39527&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39527&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39527&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39527&r=mysqlcfg
