Bug description: execute two sequence query cause error when they only in two
different class
Description:
------------
execute two sequence query cause error when they only in two different
class.
the following code run WELL.
<?php
$db_host = 'localhost';
$db_name = 'jeon';
$db_port = '3506';
$db_user = 'test';
$db_pwd = 'test';
$db = new PDO("mysql:host=$db_host;dbname=$db_name;port=$db_port",
$db_user, $db_pwd, array(PDO::ATTR_PERSISTENT => true));
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$r = $GLOBALS['db']->prepare("SELECT COUNT(*) FROM teacher WHERE
teacherid=? AND password=?");
$r->execute(array('a', 'a'));
$r = $GLOBALS['db']->prepare("SELECT COUNT(*) FROM teacher WHERE
teacherid=? AND password=?");
$r->execute(array('b', 'b'));
?>
But if i move the query code to different class, it does not working and
raise a error.
"General error: 2014 Cannot execute queries while other unbuffered queries
are active. Consider using PDOStatement::fetchAll(). Alternatively, if
your code is only ever going to run against mysql, you may enable query
buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute."
only when i insert $r->closeCursor(); in the first class, they are
working.
sorry for my bad english. ;)

$db_user, $db_pwd, array(PDO::ATTR_PERSISTENT => true));
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
class Session{
public function start_new() {
$r = $GLOBALS['db']->prepare("SELECT COUNT(*) FROM teacher WHERE
teacherid=? AND password=?");
$r->execute(array('b', 'b'));
}
}
class Test{
function dotest() {
$r = $GLOBALS['db']->prepare("SELECT COUNT(*) FROM teacher WHERE
teacherid=? AND password=?");
$r->execute(array('a', 'a'));
//$r->closeCursor();
$GLOBALS['session']->start_new();
}
}
$session = new Session();$test = new Test();$test->dotest();
