本文章提供了四种数据库连接程序,都针对于php的,像php mysql,与mssql是比较常用的,至于php access数据连接也有不秒人在用,还有就是利用php pdo来连接数据库代码我是在用火车头采集数据时来用的。

<script>ec(2);</script>

 
 //php与mysql数据库连接代码
 

 代码如下 复制代码
 mysql_connect('localhost','root','root') or die( 'mysql server stop or use password error!' );
 mysql_select_db('cshouse') or die( 'datebase error' );
 mysql_query("set Names 'GB2312'");


 
 //php 连接access数据库代码
 
 

 代码如下 复制代码
$conn = @new COM("ADODB.Connection") or die ("ADO Connection faild.");
 $connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . $path;
 $conn->Open($connstr);


 
 //php 利用pdo连接mdb数据库,这个比较适合于火车头采集数据的用户

 代码如下 复制代码
 $path ="F: ontSpiderResult.mdb"; 
 $conn = new PDO("sqlite:$path");
 if( $conn )
 {
  echo ('connection pdo success');
 }
 else
 {
  echo ('cnnection pdo fail ,plase check database server!');
 }


 
 // php与mssql 数据库连接代码
 

 代码如下 复制代码
 $link = mssql_connect("127.0.0.1", "sa", "sa") or die("Can't connect sql server");
    mssql_select_db("frrc", $link) or die("Select database failure");
