php language realizes blog homepage source code

PHP is an open source scripting language widely used in Web development. It has the advantages of flexible use, easy to learn and use. This article will introduce how to use PHP language to implement the source code of blog homepage.

First of all, it needs to be made clear that a blog homepage usually includes the following modules: navigation bar, article list, categories, tags, search box, etc.

1. Navigation bar

The navigation bar usually contains menus such as the website homepage, article list, and about me. The following is the PHP code to implement the navigation bar:

<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
  <div class="container">
    <a class="navbar-brand" href="/">My Blog</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarResponsive">
      <ul class="navbar-nav ml-auto">
        <li class="nav-item active">
          <a class="nav-link" href="/">首页
            <span class="sr-only">(current)</span>
          </a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="/articles">文章列表</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="/about">关于我</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

2. Article list

The article list usually includes the article title, cover image, publication date, abstract, etc. The following is the PHP code to implement the article list:

<div class="container">
  <div class="row">
    <?php
      $articles = get_articles(); // 获取文章列表数据
      foreach ($articles as $article) {
    ?>
    <div class="col-lg-4 col-md-6 mb-4">
      <div class="card h-100">
        <a href="/article/<?php echo $article['id']; ?>"><img class="card-img-top" src="<?php echo $article['cover_image']; ?>" alt=""></a>
        <div class="card-body">
          <h4 class="card-title">
            <a href="/article/<?php echo $article['id']; ?>"><?php echo $article['title']; ?></a>
          </h4>
          <p class="card-text"><?php echo $article['summary']; ?></p>
        </div>
        <div class="card-footer">
          <small class="text-muted"><?php echo $article['created_at']; ?></small>
        </div>
      </div>
    </div>
    <?php
      }
    ?>
  </div>
</div>

The get_articles() function here is a custom function to obtain the article list, which needs to call the database or other interfaces in the background to obtain data.

3. Categories

Categories usually display the categories of blog posts so that readers can understand the main line of content of the blogger. The following is the PHP code to implement classification:

<div class="card my-4">
  <h5 class="card-header">分类</h5>
  <div class="card-body">
    <div class="row">
      <?php
        $categories = get_categories(); // 获取分类数据
        foreach ($categories as $category) {
      ?>
      <div class="col-lg-6">
        <ul class="list-unstyled mb-0">
          <li>
            <a href="/categories/<?php echo $category['id']; ?>"><?php echo $category['name']; ?></a>
          </li>
        </ul>
      </div>
      <?php
        }
      ?>
    </div>
  </div>
</div>

Similarly, the get_categories() function is a custom function to obtain category data.

4. Tags

Tags usually display the tags of bloggers’ blog posts so that readers can understand the topic of the blog post. The following is the PHP code to implement tags:

<div class="card my-4">
  <h5 class="card-header">标签</h5>
  <div class="card-body">
    <div class="row">
      <?php
        $tags = get_tags(); // 获取标签数据
        foreach ($tags as $tag) {
      ?>
      <div class="col-lg-6">
        <ul class="list-unstyled mb-0">
          <li>
            <a href="/tags/<?php echo $tag['id']; ?>"><?php echo $tag['name']; ?></a>
          </li>
        </ul>
      </div>
      <?php
        }
      ?>
    </div>
  </div>
</div>

Similarly, the get_tags() function is a custom function to obtain tag data.

5. Search box

The search box usually provides the function of searching blog posts, allowing users to quickly find information. The following is the PHP code to implement the search box:

<form class="form-inline my-2 my-lg-0" action="/search" method="GET">
  <input class="form-control mr-sm-2" type="search" placeholder="搜索" name="keyword" required>
  <button class="btn btn-outline-success my-2 my-sm-0" type="submit">搜索</button>
</form>

Here we use HTTP GET request to pass the search keywords to the server.

The above is the PHP code to implement the blog homepage. Of course, the specific implementation still needs to be adjusted and modified according to actual needs. If you are developing your own blog site, I hope this article will be helpful to you.
