本文實例講述了php在數(shù)據(jù)庫抽象層簡單使用PDO的方法。分享給大家供大家參考，具體如下：
測試代碼如下:

<?php/**************************@Filename: pdotest.php@Content : PDO操作MySQL,Access（測試）**************************/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;?> |
測試環(huán)境:
php.ini文件: 打開 extension=php_pdo_odbc.dll 去掉分號 打開aceess數(shù)據(jù)庫驅(qū)動
mysql 默認(rèn)打開的
訪問路徑:
mysql數(shù)據(jù)庫
http://192.168.1.21/lava_guess2009/test/pdo/pdotest.php?db=mysql
aceess 數(shù)據(jù)庫
http://192.168.1.21/lava_guess2009/test/pdo/pdotest.php
特點: 使用不同數(shù)據(jù)庫只要改動連接驅(qū)動即可,代碼不用作任何改變,也就是抽象層的好處.
希望本文所述對大家php程序設(shè)計有所幫助。
