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.

<?php
//php与mysql数据库连接代码
mysql_connect(&#39;localhost&#39;, &#39;root&#39;, &#39;root&#39;) or die(&#39;mysql server stop or use password error!&#39;);
mysql_select_db(&#39;cshouse&#39;) or die(&#39;datebase error&#39;);
mysql_query("set Names &#39;GB2312&#39;");
//php 连接access数据库代码
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
$path = "F:\ontSpiderResult.mdb";
$conn = new PDO("sqlite:$path");
if ($conn) {
    echo (&#39;connection pdo success&#39;);
} else {
    echo (&#39;cnnection pdo fail ,plase check database server!&#39;);
}
// php与mssql 数据库连接代码
$link = mssql_connect("127.0.0.1", "sa", "sa") or die("Can&#39;t connect sql server");
mssql_select_db("frrc", $link) or die("Select database failure");
Copy after login
