Example #1 mssql_min_message_severity() example
<?php
// Connect to MSSQL
mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
// Set the minimum message severity to 17, this
// will not show any messages issued by the underlaying
// API when we select a non-existent database below
mssql_min_message_severity(17);
// Select a non-existent database
mssql_select_db('THIS_DATABASE_DOES_NOT_EXISTS');
?>
以上例程会输出：
mssql_select_db(): Unable to select database: THIS_DATABASE_DOES_NOT_EXISTS

very useful function to prevent the silly "message: blah blah blah" lines issued by the DB layer.
Just set the level to 17 and mssql_select_db() will (at last) leave you alone ;-)
