如何通过PHP和UniApp实现数据的搜索与筛选

<?php
// 假设我们有一个名为data的数组，它存储了我们要搜索和筛选的数据
$data = [
    ['id' => 1, 'name' => '张三', 'age' => 20, 'gender' => '男'],
    ['id' => 2, 'name' => '李四', 'age' => 25, 'gender' => '女'],
    ['id' => 3, 'name' => '王五', 'age' => 30, 'gender' => '男'],
    // 这里可以继续添加更多的数据
];

// 处理搜索和筛选请求
if (isset($_GET['keyword'])) {
    $keyword = $_GET['keyword'];
    $result = array_filter($data, function($item) use ($keyword) {
        return strpos($item['name'], $keyword) !== false;
    });
    echo json_encode($result);
} else {
    echo json_encode($data);
}
?>

<template>
  <div class="container">
    <input type="text" v-model="keyword" @input="search">
    <ul>
      <li v-for="item in items" :key="item.id">
        {{item.name}}
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      keyword: '',
      items: []
    }
  },
  methods: {
    search() {
      uni.request({
        url: 'http://yourdomain.com/search.php',
        data: {
          keyword: this.keyword
        },
        success: (res) => {
          this.items = res.data;
        }
      });
    }
  }
}
</script>
