I'm afraid you'll have to upgrade to PHP5 in order to be able to use MySQLi, which
supports this and has mysqli_next_result() method.

Description:
------------
From PHP I cannot call two stored procedure in the same connection (I guess it depends on the fact
they are returning MULTI_RESULTS, it doesn't happen with normal SELECTs)
When I run the second one I get the following error: "Commands out of sync; you can't run
this command now".
I made a lot of tests with different MySQL versions, at the moment I'm running a 5.0.27 built
from source and PHP 4.4.4 built from source and linked to 5.0.27 (not using the bundled library) and
I get that error but, for example, I got it working with client libraries from MySQL 5.1.7 beta (but
not with 5.1.12 beta).
I already posted this bug to MySQL but they closed it telling it's not a bug
(http://bugs.mysql.com/?id=24783).
They pointed me at http://dev.mysql.com/doc/refman/5.0/en/c-api-multiple-queries.html
but I cannot find a PHP equivalent for mysql_next_result
Reproduce code:
---------------
#!/usr/bin/php -q
<?php
define('CLIENT_MULTI_RESULTS', 131072);
$conn = mysql_connect("localhost", "root", "", 1 ,
CLIENT_MULTI_RESULTS) or die(mysql_error());
mysql_select_db("tester") or die(mysql_error());
$query = "CALL test_proc('webrainstorm')";
for ($i = 1; $i < 5; $i++) {
$ret = mysql_unbuffered_query($query) or
die(mysql_error()."\n");
while ($row = mysql_fetch_array($ret, MYSQL_ASSOC)) {
foreach ($row as $col) {
echo "$col\t";
}
echo "\n";
}
mysql_free_result($ret);
unset($ret);
}
mysql_close($conn);
?>
Find SQL test script at http://www.webrainstorm.it/tmp/test.sql
Expected result:
----------------
# ./test.php
enabled
enabled
enabled
enabled
Actual result:
--------------
# ./test.php
enabled
Commands out of sync; you can't run this command now
