Description:
------------
I have just upgraded to php 5.0.3 and a simple if statement based on the identifier that worked with php 5.0.2 no longer works. I have now downgraded back to php 5.0.2 and everything is working fine again. when trying a print of $result in 5.0.2 i am returned a '1' character, when trying the same in 5.0.3 the $result variable is empty. 
I have checked the database and the query in running correctly and the field is being updated.
May be a case that the function has changed and its not in the online documentation yet?

Reproduce code:
---------------
$numero= mssql_connect($dbserver,$dbuser,$dbpass)
or die ("Unable to connect to database server");

$query = "update test_table set phonenum = '$phonenum' where ind = '$ind'";
$result = mssql_query($query,$numero);
if($result){
      print "update success!";
}
else{
      print "update failure!";
}

Expected result:
----------------
update success!

Actual result:
--------------
update failure!
