2.测试

<?php

include "sqlsrv.class.php";

$sql=new sqlsrv("192.168.1.109","sa","xxx","test");

$strsql="select @@version";
echo "<pre><h2>sqlsrv test</h2>";
echo "<h3> rows:</h3>";
var_dump($sql->count($strsql));
echo "<h3> sql:</h3>";
print_r($sql->sql_log);
echo "<h3> errors:</h3>";
print_r($sql->error_log);
echo "<h3> sqlsrv:</h3>";
print_r($sql);

?>
