用php编程语言写程序：连接MySQL数据库，并插入数据库表------作者姓名，提交时间，标题，文章内容。

<?php
// 连接MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 准备要插入的数据
$author = "作者姓名";
$submitTime = date("Y-m-d H:i:s");
$title = "标题";
$content = "文章内容";

// 构造插入数据的SQL语句
$sql = "INSERT INTO your_table (author, submit_time, title, content) VALUES ('$author', '$submitTime', '$title', '$content')";

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

// 关闭数据库连接
$conn->close();
?>
