列表代码
<?php $con = mysql_connect("localhost:3306","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $result = mysql_query("SELECT * FROM user"); echo "<table border='1'> <tr> <th>Username</th> <th>Password</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['username'] . "</td>"; echo "<td>" . $row['password'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?>
删除
<?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); mysql_query("DELETE FROM user WHERE username = '$_POST[username]'"); mysql_close($con); ?>
添加
<?php $con = mysql_connect("localhost:3306","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $sql = "INSERT INTO user (username,password) VALUES ('$_POST[username]','$_POST[password]')"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } echo "1 record added"; mysql_close($con); ?>
