When a stored procedure returns a resultset, MySQL returns at least two
resultsets: first for the SELECT CALL inside the stored procedure. 2nd
for the call of the stored procedure itself (2nd usually is only an OK
or ERR packet)

mysqli_query fetches only one resultset, the second is still on socket:
subsequent mysqli_ calls will fail, cause the sockets is still blocked.

Therefore you should use mysqli_next_result and mysqli_multi_query
instead.

Why I should use mysqli_multi_query()? Where is it documented, that I
should use mysqli_multi_query() for stored procedures?

But the following code with mysqli_multi_query() doesn't work either:

---
// $db is mysqli object
if ($db->multi_query('CALL test_proc(1); CALL test_proc(1);')) {
if ($result = $db->store_result()) {
$res = $result->fetch_assoc();
print_r($res);
$result->close();
}
else
echo 'No result!';
$db->next_result();
if ($result = $db->store_result()) {
$res = $result->fetch_assoc();
print_r($res);
$result->close();
}
else
echo 'No result';
}
else
echo ''.$db->error.'';
-

Produces the following output:
-
Array
(
[id] => 1
[txt] => test1
)

No result
-

(Expected was two identical results)

For calling stored procedures you have to use mysqli_multi_query.

Additional thing - when you don't send any requests to Apache and MySQL
for some time, sample script seems to work. But just for one request,
when you press "Refresh" in your browser and run it second time, it
gives output i've posted.

Description:

Create MySQL test table and procedure:
--
CREATE TABLE `test_table` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `txt` varchar(255) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO test_table (txt) VALUES ('test1');

CREATE PROCEDURE `test_proc`(IN p_id INT(10) UNSIGNED) READS SQL DATA
DETERMINISTIC
BEGIN
   SELECT * FROM test_table WHERE id = p_id; 
END


Reproduce code:
---
// $db is mysqli object

if ($result = $db->query('CALL test_proc(1);')) {
$res = $result->fetch_assoc();
print_r($res);
$result->close();
}
else
echo ''.$db->error.'';

if ($result = $db->query('CALL test_proc(1);')) {
$res = $result->fetch_assoc();
print_r($res);
$result->close();
}
else
echo ''.$db->error.'';


Expected result:

Array
(
[id] => 1
[txt] => test1
)

Array
(
[id] => 1
[txt] => test1
)

Actual result:
--
Array
(
[id] => 1
[txt] => test1
)

Lost connection to MySQL server during query
