為了能讓PHP連接MSSQL,系統需要安裝MSSQL,PHP,且在PHP.ini中的配置中,將
?????? ;extension=php_mssql.dll前面的;去掉

?????? 1.連接MSSQL
?????? $conn=mssql_connect("實例名或者服務器IP","用戶名","密碼");

?????? //測試連接
?????? if($conn)
?????? {
?????? echo "連接成功";
?????? }

?????? 2.選擇要連接的數據庫
?????? mssql_select_db("dbname");

?????? 3.執行查詢
?????? $rs = mssql_query("select top 1 id,username from tbname",$conn);
?????? 或者直接執行update,insert等語句,可以不用為返回結果賦值
?????? mssql_query("update tbname set username='niunv' where id=1");

?????? 4.獲取記錄集行數
?????? echo mssql_num_rows($rs);

?????? 5.獲取記錄集
?????? if($row=mssql_fetch_array($rs))
?????? {
?????? $id = $row[0];//獲取ID字段值
?????? $username = $row[1];//獲取username字段值
?????? }

?????? 6.獲取新增記錄的ID
?????? 將id字段設置為IDENTITY字段,執行insert語句以后,就會產生一個 @@IDENTITY 全局變量值,查詢出來就是最后一條新增記錄的ID了.
?????? mssql_query("insert into tbname(username) values ('nv')",$conn);?
?????? $rs = mssql_query("select @@IDENTITY as id",$conn);
?????? if($row=mssql_fetch_array($rs))
?????? {
?????? echo $row[0];
?????? }

?????? 7.釋放記錄集
?????? mssql_free_result($rs);

?????? 8.關閉連接
?????? mssql_close($conn);?
???????

?????? 注:用PHP操作MSSQL比在ASP連接MYSQL要簡單,所以,當需要MSSQL與MYSQL并存時,用PHP連接MSSQL來操作MYSQL與MSSQL并存比較簡單好用.如果是ASP連接MYSQL,需要安裝一個MYSQL驅動,默認windows的ODBC沒有安裝,很遺憾...?
???????
???????
???????
? 1.在web服務器上至少安裝了mssql的客戶端?????
? 2.打開php.ini把;extension=php_mssql.dll?? 前面的分號去掉???
??????? 有必要話：需要制定extension_dir???
? 3.推薦使用?? php<=4.0.9???? <=5.0.3目前?? 我還沒有連接成功過4.010和?? 5.0.3???
? 4.數據庫的?? 連接分頁可以?? 到???? phpe.net上獲取到相應的class???
? 下面是我根據那里?? 修改的?? 一個class???
