How to use PHP and Vue to implement data conversion function

In modern web development, data conversion and processing are very common requirements. In this article, we will focus on how to use PHP and Vue to implement data conversion functions. Specifically, we will show a practical case involving converting an XML format data into JSON format data and displaying it on the front-end page through Vue.

1. Preparation

Before we start, we need to ensure that PHP and Vue.js have been installed in the system and be familiar with the basic PHP and Vue syntax.

2. Case Background

Suppose we have a data file in XML format, which contains some student information, such as name, age, gender, etc. Our goal is to convert this data into JSON format and display it on the front-end page.

3. Implementation steps

Create a PHP script to read XML data and convert it to JSON format. The following is a simple example:

<?php

$xmlString = file_get_contents('students.xml'); // 读取XML数据
$xml = simplexml_load_string($xmlString); // 将XML字符串转换为SimpleXMLElement对象
$json = json_encode($xml); // 将SimpleXMLElement对象转换为JSON字符串

echo $json; // 输出JSON数据

?>

Create a Vue component to load and display the converted JSON data. The following is a simple example:

<template>
  <div>
    <h1>学生信息</h1>
    <ul>
      <li v-for="student in students" :key="student.name">
        <p>姓名：{{ student.name }}</p>
        <p>年龄：{{ student.age }}</p>
        <p>性别：{{ student.gender }}</p>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      students: []
    }
  },
  mounted() {
    this.loadStudents();
  },
  methods: {
    async loadStudents() {
      const response = await fetch('students.php'); // 调用PHP脚本来获取JSON数据
      const data = await response.json(); // 解析JSON数据
      this.students = data.students; // 将数据赋值给Vue组件的students属性
    }
  }
}
</script>

4. Code Description

The file_get_contents() function in the PHP script is used to read XML files Content.
simplexml_load_string()The function converts an XML string into a SimpleXMLElement object to facilitate subsequent processing.
json_encode() Function converts a SimpleXMLElement object into a JSON string.
fetch('students.php') in the Vue component is used to call the PHP script to obtain JSON data.
response.json()Parses the response data into a JSON object.
this.students = data.studentsAssign JSON data to the students property of the Vue component.

5. How to use

Save the above code as students.php and Students.vue files.
Introduce Vue.js and Students.vue components into the HTML page.
Create an HTML element containing the <students></students> node to render the Students.vue component.

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>数据转换示例</title>
  <script src="vue.js"></script>
</head>
<body>
  <div id="app">
    <students></students>
  </div>

  <script src="Students.vue"></script>
  <script>
    new Vue({
      el: '#app'
    });
  </script>
</body>
</html>
