php怎么增加多行数据?
mysqli_multi_query() 函数可用来执行多条SQL语句。
以下实例向 "MyGuests" 表添加了三条新的记录:
实例 (MySQLi - 面向对象)
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建链接 $conn = new mysqli($servername, $username, $password, $dbname); // 检查链接 if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com');"; $sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Mary', 'Moe', 'mary@example.com');"; $sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Julie', 'Dooley', 'julie@example.com')"; if ($conn->multi_query($sql) === TRUE) { echo "新记录插入成功"; } else { echo "Error: " . $sql . "<br>" . $conn->error; } $conn->close(); ?>
Note 请注意,每个SQL语句必须用分号隔开。
实例 (MySQLi - 面向过程)
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建链接 $conn = mysqli_connect($servername, $username, $password, $dbname); // 检查链接 if (!$conn) { die("连接失败: " . mysqli_connect_error()); } $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com');"; $sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Mary', 'Moe', 'mary@example.com');"; $sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Julie', 'Dooley', 'julie@example.com')"; if (mysqli_multi_query($conn, $sql)) { echo "新记录插入成功"; } else { echo "Error: " . $sql . "<br>" . mysqli_error($conn); } mysqli_close($conn); ?>
