本文给大家分享的是使用php结合mysql实现简单的增删改查的功能的代码，非常的简单实用，有需要的小伙伴可以参考下。
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);
- ?>
修改
- <?php
- $con = mysql_connect("localhost","root","");
- if (!$con) {
- die('Could not connect: ' . mysql_error());
- }
- mysql_select_db("test", $con);
- mysql_query("UPDATE user SET password = '$_POST[password]' WHERE username = '$_POST[username]'");
- mysql_close($con);
- ?>
