测试代码如下:
<?php
/**************************
@Filename: pdotest.php
@Content : PDO操作MySQL,Access（测试）
**************************/
if($_GET['db'] == 'mysql')
{
$dns = 'mysql:host=localhost;dbname=test';
$dbuser = 'root';
$dbpass = 'root';
$db = new PDO($dns,$dbuser,$dbpass);
}
else
{
$db = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=".getcwd()."//test.mdb");
}
if($_POST['reg'])
{
$db->exec("INSERT INTO t_user (name,email) VALUES ('".$_POST['name']."','".$_POST['email']."') ;");
// header('Location:'.$_SERVER['PHP_SELF']);
?>
<a href="pdotest.php">返回</a>
<?
}
else
{
$html = '
<div id="new">
<form action="'.$_SERVER['REQUEST_URI'].'" method="post">
Name: <input type="text" name="name" size="10" />
Email: <input type="text" name="email" size="15" />
<input type="submit" name="reg" value="Register" />
</form>
</div>
';
$re = $db->query("SELECT uid,name,email FROM t_user ORDER BY email ;");
while($rs = $re->fetch())
{
$userlisthtml .= '
<tr><td>'.$rs['uid'].'</td><td>'.$rs['name'].'</td><td>'.$rs['email'].'</td></tr>';
}
$html .= '
<div id="list">
<table border="1">
<caption>User List</caption>
<thead>
<tr><th>ID</th><th>Name</th><th>Email</th></tr>
</thead>
<tbody>'.$userlisthtml.'
</tbody>
</table>
</div>
';
}
echo $html;
?>
测试环境:
php.ini文件: 打开 extension=php_pdo_odbc.dll 去掉分号 打开aceess数据库驱动
mysql 默认打开的
访问路径:
mysql数据库
http://192.168.1.21/lava_guess2009/test/pdo/pdotest.php?db=mysql
aceess 数据库
http://192.168.1.21/lava_guess2009/test/pdo/pdotest.php
特点: 使用不同数据库只要改动连接驱动即可,代码不用作任何改变,也就是抽象层的好处.
