How to use PHP and Vue.js to create statistical charts with animated effects

In modern data visualization, statistical charts are a very common and important Display mode. PHP and Vue.js are two very popular programming languages and frameworks, which are very convenient for building dynamic data visualization charts. This article will introduce how to use PHP and Vue.js to create statistical charts with animated effects, and provide corresponding code examples.

Preparation
First, you need to ensure that PHP and Vue.js have been installed in your development environment. You can install it from the official website or using a package manager. Additionally, you will need a web server (such as Apache) to run the PHP files.
Data Preparation and Processing
Before you start building a chart, you need to prepare and process the data you want to display. You can get data from the database or through API calls. In this example, we will use a simple PHP array to simulate the data. Please prepare your data according to your actual situation.

<?php
// 模拟数据
$data = [
  ['label' => 'Apple', 'value' => 20],
  ['label' => 'Orange', 'value' => 10],
  ['label' => 'Banana', 'value' => 15],
  // 其他数据...
];
?>

Create HTML and Vue.js template
Next, we will create an HTML file that includes a container element to hold our chart and use Vue.js Template syntax binds data and styles.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>统计图表</title>
  <style>
    /* 样式 */
    .chart {
      width: 400px;
      height: 300px;
      padding: 20px;
      background-color: #f1f1f1;
      border-radius: 10px;
      box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
    }
    .bar {
      height: 20px;
      margin-bottom: 10px;
      background-color: #2196f3;
      transition: width 0.5s ease-in-out;
    }
  </style>
</head>
<body>
  <div id="app">
    <div class="chart">
      <!-- 使用Vue.js循环渲染数据 -->
      <div v-for="item in data" :key="item.label">
        <div class="bar" :style="{ width: item.value + '%' }"></div>
        <span>{{ item.label }}</span>
      </div>
    </div>
  </div>
  
  <!-- 引入Vue.js -->
  <script src="https://cdn.jsdelivr.net/npm/vue@2.6.11"></script>
  <!-- 引入统计图表脚本 -->
  <script src="chart.js"></script>
</body>
</html>

Create Vue.js component
Next, we will create a Vue.js component to process data and provide animation effects. In this component, we will use Vue’s reactive data binding to update the chart.

// chart.js

// 引入数据
<?php include('data.php'); ?>

// 创建Vue实例
new Vue({
  el: '#app',
  data: {
    data: <?php echo json_encode($data); ?> // 将PHP数据转为JS对象
  },
  mounted() {
    // 在视图渲染完毕后，添加动画效果
    this.addAnimation();
  },
  methods: {
    addAnimation() {
      const bars = this.$el.querySelectorAll('.bar');
      bars.forEach((bar, index) => {
        setTimeout(() => {
          bar.style.width = this.data[index].value + '%';
        }, 100 * index); // 根据索引延迟执行动画
      });
    }
  }
});

Run and Test
Now you have completed building the entire chart. Save the above HTML file as chart.html and chart.js as chart.js, and place them in the same directory as the data file data.php. Then, access the chart.html file through the web server, and you will see a statistical chart with animated effects.

You can adjust the style and animation effects as needed to meet your needs. In addition, you can also consider encapsulating the data acquisition and processing process into an independent PHP function to facilitate reuse in different pages and applications.

Summary
This article introduces how to use PHP and Vue.js to create statistical charts with animated effects. Obtain and process data through PHP, and use Vue.js to achieve data binding and animation effects. You can easily build dynamic and interactive charts. I hope this article was helpful to you and I wish you success in your data visualization journey!
