MySQL Insert Multiple

Inserting Multiple Records into a MySQL Database using PHP （使用PHP将多个记录插入MySQL数据库）

Inserting multiple records into a database at once can greatly increase the efficiency of your application, particularly when dealing with large amounts of data. In this article, we will show you how to insert multiple records into a MySQL database using PHP. （同时将多个记录插入数据库可以大大提高应用程序的效率，特别是在处理大量数据时。在本文中，我们将向您展示如何使用PHP将多个记录插入MySQL数据库。）

Establishing a Connection #

Establishing a Connection （建立联系）

Before we can insert records into the database, we need to establish a connection to the database using PHP’s mysqli extension. Here is an example of how to establish a connection to a MySQL database:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$conn) {
   die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>

Writing the SQL Statement #

Writing the SQL Statement （编写SQL语句）

The next step is to write a SQL statement to insert multiple records into the database. In order to insert multiple records, we need to use the INSERT INTO statement multiple times. Here is an example of how to insert multiple records into a MySQL database:

<?php
$sql = "INSERT INTO table_name (column1, column2, column3)
VALUES ('value1', 'value2', 'value3'),
      ('value4', 'value5', 'value6'),
      ('value7', 'value8', 'value9')";
?>

Executing the SQL Statement #

Executing the SQL Statement （执行SQL语句）

The next step is to execute the SQL statement. This is done using the mysqli_query() function, which requires the following parameters:

• The connection to the database （-与数据库的连接）

• The SQL statement to be executed （-要执行的SQL语句）

Here is an example of how to execute the SQL statement:

<?php
if (mysqli_query($conn, $sql)) {
   echo "Records inserted successfully.";
} else {
   echo "Error inserting records: " . mysqli_error($conn);
}
?>

Closing the Connection #

Closing the Connection （关闭连接）

After inserting the records into the database, it is important to close the connection to the database to avoid any security risks. This is done by using the mysqli_close() function, which requires the following parameter:

• The connection to the database （-与数据库的连接）

Here is an example of how to close the connection to the database:

<?php
mysqli_close($conn);
?>

Conclusion （小结）

In this article, we have shown you how to insert multiple records into a MySQL database using PHP. By following these steps, you should be able to insert multiple records into your database quickly and efficiently. It is important to note that the exact steps may vary depending on the specific database management system that you are using, so be sure to consult the documentation for your system for more information. （在本文中，我们向您展示了如何使用PHP将多个记录插入MySQL数据库。通过执行这些步骤，您应该能够快速有效地将多个记录插入数据库。请注意，具体步骤可能因您使用的特定数据库管理系统而异，因此请务必查阅系统文档以获取更多信息。）
