Hello Sirs.
When I use sybase_affected_rows()  fucntion for our project, the function call failed.
Following is the code snippet:

$query = "insert into form_form values('company', 'lingqin', 'file', 'email@mtcibs.com', 'subject')";
$conn = sybase_connect($server, $user, $pass);
sybase_select_db($dbname, $conn);
$result = sybase_query($query, $conn);
$rows = sybase_affected_rows($result);

When I run the above script, I got the following error:
Fatal error: Call to undefined function: sybase_affected_rows() in /webdev/skmtest/rw/docroot/sybtest.phtml on
line 9

But, the PHP manul tells me the above function can be used by PHP 3>= 3.0.6, PHP 4
We are using PHP Version 4.0.4pl1.

Please let  me know what's the problem.
Thanks a lot.
