Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

The storedprocedure looks like this:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
CREATE PROCEDURE [dbo].[test]
(
   @sval int
) AS
return @sval+10


And the php code looks like this

<?
	$conn = mssql_connect("host","user","pass");
	mssql_select_db("dbscheme", $conn);
	
	$sp = mssql_init("test", $conn); // stored proc name
	$query  = mssql_execute($sp) or die("oops");

?>

is fails in this line "$query  = mssql_execute($sp) or die("oops");"

Sorry the code schould look like this

<?
	$conn = mssql_connect("host","user","pass");
	mssql_select_db("dbscheme", $conn);
	$int=10;
	$sp = mssql_init("test", $conn); // stored proc name
	mssql_bind($sp, "@sval ",$int,SQLINT4);
	$query  = mssql_execute($sp) or die("oops");
?>

I've tested your sample code and it works just fine om my system. I did modify it to get the return value back though:

$int=10;
$sp = mssql_init("test", $con); // stored proc name
mssql_bind($sp, "@sval", $int, SQLINT4);
mssql_bind($sp, "RETVAL", $ret, SQLINT4);
$query  = mssql_execute($sp) or die("oops");
echo "$ret\n";	
mssql_close($con);

can i see your phpinfo ?

No feedback was provided for this bug for over a week, so it is
being suspended automatically. If you are able to provide the
information that was originally requested, please do so and change
the status of the bug back to "Open".

I had the same problem and managed to solve as follows:

$sp = "procedurename";
$compId=1000;
$sql = "$sp $compId";
$query = mssql_query($sql);
$data = mssql_fetch_array($query);

This is not the most elegant way (do not use bind), but it works.
