Description:
------------
Previous to 4.3.10, mssql_query returned the following:
=== a valid result set OR
=== true if successful but no result set OR
=== false if an error occurred

Therefore if one wanted to check for an error one would use:
if(mssql_query === false) { echo 'yikes!'; }

Since 4.3.10, when using mssql_query to execute an INSERT query, a result of false is returned even if the row was successfully inserted.

Reproduce code:
---------------
$query = "INSERT INTO DOGBERT (CATBERT) VALUES ('DILBERT')";
$rs = mssql_query($query);
if($rs === false) {
   echo 'This should only print when there is an error';
}


Expected result:
----------------
$rs should only evaluate === false when there is an error (according to the docs)

Actual result:
--------------
$rs always evaluates === false on INSERT
