[PHP-DB] Problem with PHP 4.4.4 and MSSQL in Centos
Hi all!
I've stepped into an annoying problem when trying to fetch the tuples
returned by a stored procedure in a MSSQL database from a PHP program
running in a Centos Linux server running PHP 4.4.4.
The stored procedure returns an arbitrary number of tuples, and my code
is only working when the SP returns one row.
The code I'm using, simplified, follows:
$db_conn = mssql_connect (server, user, passwd);
mssql_select_db(db,$db_conn);
$query = Exec stored_procedure '$par1', '$par2';
$result = mssql_query ($query);
while ($row = mssql_fetch_array ($result)) {
echo $row[COL1];
echo br/;
}
If stored_procedure () returns only one row, the code executes without
any problem. However, if there are more than one rows to be returned,
the program not only blocks, but also eats all the server's memory.
I've run this program also in Ubuntu with PHP 4.4, and it works without
any problem, so I'm thinking it may be either a configuration problem of
the centos server, or a bug in the PHP version.
Do you have any hint to solve this? I would appreciate any advice.
Thanks in advance,
Claudio

Hi Claudio,
1) Check the version of FreeTDS on both systems.
2) Check the freetds.conf file for differences (use the sam TDS version)
3) Check that php is compiled using --with-mssql on both systems
(--with-sybase will give you aliases to some mssql_( functions but not
all)

Now it works perfectly. Thanks for your suggestions. Anyway, I wouldn't expect php to hang and kill my server if compiled with --sybase. Maybe just a runtime error would be ok, but a hang like that, it's a bug to me. I would gladly report it, if I knew where should I. Do you think it may be in freeTDS or PHP itself? I am not really into PHP internals.

Hi Claudio, bugs.php.net would be the place to report the bug. As both the MSSQL and Sybase extensions are using the same FreeTDS library I would think the bug is in the Sybase extension. You will get more mssql_* functions with the MSSQL extension, and much better support for storred procedures so I think you will be happy about the change. - Frank Hi Frank, El vie, 12-01-2007 a las 10:49 -0800, Frank M.
