以php为后端，vue为前端的租房微信小程序

租房微信小程序是一个非常有用的应用，它不仅可以帮助人们快速找到心仪的房屋，还可以提供便捷的房屋租赁服务。本文将介绍如何使用PHP作为后端语言和Vue作为前端框架来开发一个租房微信小程序。

1. 环境搭建

首先，需要在本地或云上安装并配置PHP和Vue环境。可以使用XAMPP、WAMP、MAMP等集成的开发环境，也可以手动安装和配置PHP环境。Vue则需要使用Node.js提供的npm包管理器进行安装和配置。

2. 创建数据库

在PHPMyAdmin或其他数据库管理工具中创建一个名为"rental"的数据库，并创建一个名为"house"的表，用于存储房屋信息。表结构如下：

| id | title | price | area | address | image | description |

3. 编写后端代码

使用PHP编写后端代码，建立与数据库连接，并提供RESTful API。代码示例：

    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/json; charset=UTF-8");

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

    $conn = new mysqli($servername, $username, $password, $dbname);

    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }

    $method = $_SERVER['REQUEST_METHOD'];

    if($method == "GET") {

        $sql = "SELECT * FROM house";
        $result = $conn->query($sql);

        $rows = array();

        if ($result->num_rows > 0) {
            while($row = $result->fetch_assoc()) {
                $rows[] = $row;
            }
        }

        echo json_encode($rows);

    } else if($method == "POST") {

        $data = json_decode(file_get_contents("php://input"));

        $title = $data->title;
        $price = $data->price;
        $area = $data->area;
        $address = $data->address;
        $image = $data->image;
        $description = $data->description;

        $sql = "INSERT INTO house (title, price, area, address, image, description)
        VALUES ('$title', '$price', '$area', '$address', '$image', '$description')";

        if ($conn->query($sql) === TRUE) {
            echo "New record created successfully";
        } else {
            echo "Error: " . $sql . "
" . $conn->error;
        }

    }

    $conn->close();
?>

4. 编写前端代码

使用Vue编写前端代码，实现小程序界面和数据交互。代码示例：

<template>
  <div class="house-list">
    <div class="house" v-for="house in houses" :key="house.id">
      <div class="image">
        <img :src="house.image" alt="house">
      div>
      <div class="info">
        <h3>{{ house.title }}h3>
        <p>价格：{{ house.price }}元/月p>
        <p>面积：{{ house.area }}平米p>
        <p>地址：{{ house.address }}p>
        <p>描述：{{ house.description }}p>
      div>
    div>
    <div class="add-house">
      <h3>新增房屋信息h3>
      <form @submit.prevent="submit">
        <input type="text" v-model="title" placeholder="请输入标题">
        <input type="number" v-model="price" placeholder="请输入价格">
        <input type="number" v-model="area" placeholder="请输入面积">
        <input type="text" v-model="address" placeholder="请输入地址">
        <input type="text" v-model="image" placeholder="请输入图片地址">
        <input type="text" v-model="description" placeholder="请输入描述">
        <button type="submit">提交button>
      form>
    div>
  div>
template>

<script>
export default {
  data() {
    return {
      houses: [],
      title: '',
      price: '',
      area: '',
      address: '',
      image: '',
      description: ''
    }
  },
  created() {
    this.getHouses()
  },
  methods: {
    getHouses() {
      fetch('http://localhost/rental/api.php')
        .then(response => response.json())
        .then(data => {
          this.houses = data
        })
    },
    submit() {
      let data = {
        title: this.title,
        price: this.price,
        area: this.area,
        address: this.address,
        image: this.image,
        description: this.description
      }
      fetch('http://localhost/rental/api.php', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(data)
      })
        .then(() => {
          this.getHouses()
          this.title = ''
          this.price = ''
          this.area = ''
          this.address = ''
          this.image = ''
          this.description = ''
        })
    }
  }
}
script>

5. 运行小程序

使用微信小程序开发工具创建一个新的小程序应用，并将前端代码导入。运行小程序，观察效果。

以上就是使用PHP和Vue开发租房微信小程序的详细过程。开发者可以根据自己的需求和实际情况对代码进行修改和完善。
