请问php如何面向对象操作mysql数据库呢？
$db=@new mysqli("localhost","root","123456");
If (mysqli_connect_errno()) //检查连接是否成功，mysqli_connect_errno()函数返回连接失败的错误编号。
{
echo "数据库连接失败";
eixt;
}
else
echo "数据库连接成功"
php面向对象操作mysql。我需要修改什么地方？
试修改代码如下：
?php
class mysql
{
private $host;
private $root;
private $pass;
private $conn;
private $table;
function __construct($host, $root, $pass, $table)
{
$this-host = $host;
$this-root = $root;
$this-pass = $pass;
$this-table = $table;
$this-connect();
}
function connect()
{
$this-conn = mysql_connect($this-host, $this-root, $this-pass) or die(mysql_error());
mysql_select_db($this-table, $this-conn) or die(mysql_error());
}
function query($table)
{
mysql_query($table,$this-conn);
}
function fn_inset($table, $name, $value)
{
echo "insert into $table ($name) value ($value)";
//$this-query("insert into $table ($name) value ($value)");
}
}
$db = new mysql('localhost','root','','xiaoguang');
$db-fn_inset('table', 'id,table,content,time', "'','我插入的信息','我插入的内容',time()")
?
请问如何用php面向对象操作mysql数据库？
$con=mysqli_connect("localhost","my_user","my_password","my_db");
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_query($con,"SELECT * FROM Persons");
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Glenn','Quagmire',33)");
mysqli_close($con);
请问PHP怎样用面向对象方式连接MySQL数据库?
?php
$servername = "localhost"; //你的连接地址，可以是ip
$username = "username"; //你的用户名
$password = "password"; //你的密码
$dbname = "myDB"; //你要连接数据库的名字
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn-connect_error) {
die("连接失败: " . $conn-connect_error);
}
echo "连接成功";
