Best practices for data management with PHP and Typecho

With the development of the Internet, website construction and management are becoming more and more important. As an open source blogging system, Typecho provides a simple and efficient way to build a personal blog. As a programming language widely used in server scripts, PHP complements Typecho and provides it with powerful data management functions. This article will introduce how to use PHP and Typecho to implement best practices for data management.

1. Create a database connection
   To use PHP to manage data, you first need to create a connection to the database. Here is a sample code:

<?php
$servername = "localhost";  //数据库服务器地址
$username = "root";  //数据库用户名
$password = "password";  //数据库密码
$dbname = "database";  //数据库名称

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检测连接是否成功
if ($conn->connect_error) {
  die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
?>

2. Query Database
   Next, we can use PHP to query the database and get the required data. The following is a sample code for querying the database:

<?php
$sql = "SELECT * FROM table_name";  //要查询的数据库表和字段

$result = $conn->query($sql);

if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo "字段1: " . $row["column1"]. " - 字段2: " . $row["column2"]. "<br>";
  }
} else {
  echo "没有数据";
}
$conn->close();
?>

3. Insert data
   In addition to querying data, we can also use PHP to insert data into the database. The following is a sample code:

<?php
$sql = "INSERT INTO table_name (column1, column2, column3)
VALUES ('value1', 'value2', 'value3')";

if ($conn->query($sql) === TRUE) {
  echo "数据插入成功";
} else {
  echo "数据插入失败: " . $conn->error;
}
$conn->close();
?>

4. Update and delete data
   Using PHP, you can also update and delete data in the database. The following is a sample code to update data:

<?php
$sql = "UPDATE table_name SET column1='new_value' WHERE condition";

if ($conn->query($sql) === TRUE) {
  echo "数据更新成功";
} else {
  echo "数据更新失败: " . $conn->error;
}
$conn->close();
?>

The following is a sample code to delete data:

<?php
$sql = "DELETE FROM table_name WHERE condition";

if ($conn->query($sql) === TRUE) {
  echo "数据删除成功";
} else {
  echo "数据删除失败: " . $conn->error;
}
$conn->close();
?>

5. Conclusion
   By using PHP and Typecho, we can Easily implement data management functions. Whether it is querying, inserting, updating or deleting data, PHP provides a wealth of functions and syntax to meet our needs. By using these functions flexibly, we can build a powerful website and blog system.
