PHP连接数据库之PHP连接MS SQL数据库代码方法
安装SQL服务器并添加PHP的MSSQL扩展
使用以下代码连接并测试
< ?php $myServer = localhost //主机 $myUser = sa //用户名 $myPass = password //密码 $myDB = Northwind //MSSQL库名 $s = @mssql_connect($myServer $myUser $myPass) or die(Couldnt connect to SQL Server on $myServer) $d = @mssql_select_db($myDB $s) or die(Couldnt open database $myDB) $query = SELECT TitleOfCourtesy+ +FirstName+ +LastName AS Employee $query = FROM Employees $query = WHERECountry=USA AND Left(HomePhone ) = ( ) $result = mssql_query($query) $numRows = mssql_num_rows($result) echo <h > $numRows Row ($numRows == ? : s) Returned </ h > while($row = mssql_fetch_array($result)) { echo <li> $row[Employee] </li> } ?>
PHP连接数据库之PHP连接Oracle数据库
PHP提供了两套函数与Oracle连接 分别是ORA_和OCI函数 其中ORA_函数略显陈旧 OCI函数更新据说更好一些 两者的使用语法几乎相差无几 你的PHP安装选项应该可以支持两者的使用
< ? if ($conn=Ora_Logon("user@TNSNAME" "password")) { echo "SUCCESS ! Connected to databasen" }else {echo "Failed : ( Could not connect to databasen"} Ora_Logoff($conn) phpinfo() ?> lishixinzhi/Article/program/PHP/201405/30761
