Introduction

This tutorial will guide you through PHP Build a blog from scratch. We'll cover the basics like setting up a PHP environment, connecting to a database, and building the basic pages of your blog.

Prerequisites

• PHP knowledge
• MySQL database
• Editor or IDE

Steps

1. Set up PHP environment

Install PHP and Composer (a package manager for managing PHP dependencies).

2. Create a database

Use SQL statements to create a database for storing blog posts and comments.

CREATE DATABASE blog;
USE blog;

CREATE TABLE articles (
  id INT AUTO_INCREMENT PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  content TEXT NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE comments (
  id INT AUTO_INCREMENT PRIMARY KEY,
  article_id INT NOT NULL,
  name VARCHAR(255) NOT NULL,
  content TEXT NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

3. Connect to the database

Establish a connection between PHP and the database.

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "blog";

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

// 检查连接是否成功
if ($conn->connect_error) {
  die("连接失败: " . $conn->connect_error);
}

4. Create a blog post page

Build a page to display a list of blog posts.

// 获取所有文章
$sql = "SELECT * FROM articles";
$result = $conn->query($sql);

// 输出文章列表
while ($row = $result->fetch_assoc()) {
  echo "<div class='article'>";
  echo "<h1>" . $row['title'] . "</h1>";
  echo "<p>" . $row['content'] . "</p>";
  echo "<a href='article.php?id=" . $row['id'] . "'>Read More</a>";
  echo "</div>";
}

5. Create a single post page

Build a page to display a specific blog post and comments.

// 获取文章 ID
$id = $_GET['id'];

// 获取文章详细信息
$sql = "SELECT * FROM articles WHERE id = $id";
$result = $conn->query($sql);
$article = $result->fetch_assoc();

// 获取评论
$sql = "SELECT * FROM comments WHERE article_id = $id";
$result = $conn->query($sql);
$comments = $result->fetch_all(MYSQLI_ASSOC);

// 输出文章和评论
echo "<div class='article'>";
echo "<h1>" . $article['title'] . "</h1>";
echo "<p>" . $article['content'] . "</p>";
echo "<br>";
echo "<ul>";
foreach ($comments as $comment) {
  echo "<li>" . $comment['name'] . ": " . $comment['content'] . "</li>";
}
echo "</ul>";
echo "</div>";
