Practical Guide to PHP and Vue.js: How to Apply Statistical Charting Features to Your Projects

Overview
In modern web applications, charts and statistics is very important. They help us visualize data to better understand and analyze it. In this article, we will introduce how to apply statistical chart functionality in your project using PHP and Vue.js.

Prerequisites
Before you begin, make sure you are familiar with PHP and Vue.js. In the meantime, this tutorial will use the following technologies and tools:

PHP 7
Vue.js 2
Chart.js

Step 1: Create the project structure
First, create a new project directory and create the following files and folders inside it:

index.html: for display Chart HTML file
scripts/: JavaScript file used to store Vue.js and Chart.js

Step 2: Install Chart.js
Open the terminal in the project root directory and execute the following command to install Chart.js:

$ npm install chart.js

Step 3: Create the index.html file
In the index.html file, we will use Vue.js to create A simple component and uses Chart.js to render charts. In addition, the JavaScript files of Vue.js and Chart.js need to be introduced.

<!DOCTYPE html>
<html>
<head>
  <title>统计图表功能</title>
  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
  <script src="scripts/chart.js"></script>
</head>
<body>
  <div id="app">
    <canvas id="chart"></canvas>
  </div>
  <script src="app.js"></script>
</body>
</html>

Step 4: Create app.js file
Create a JavaScript file named app.js in the scripts folder. In this file, we will create a Vue instance and use Chart.js in its mounted lifecycle hook to render the chart.

new Vue({
  el: '#app',
  mounted: function() {
    var ctx = document.getElementById('chart').getContext('2d');
    new Chart(ctx, {
      type: 'bar',
      data: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [{
          label: '数据集',
          data: [10, 20, 30, 40, 50, 60, 70],
          backgroundColor: '#FF6384',
          borderColor: '#FF6384',
          borderWidth: 1
        }]
      },
      options: {
        responsive: true,
        scales: {
          yAxes: [{
            ticks: {
              beginAtZero: true
            }
          }]
        }
      }
    });
  }
});

Step 5: Run the project
Open a terminal in the root directory and execute the following command to start a local server:

$ php -S localhost:8000

Then visit http://localhost in the browser :8000/index.html, you will see a page containing statistical charts.

Conclusion
This article introduces how to use PHP and Vue.js to apply statistical chart functions in projects.
