PHP connects to Baidu Wenxin Yiyan API to obtain data sorting and paging processing methods for specific types of sentences

With the development of the Internet, people are interested in obtaining various types of sentences. The demand for data is also increasing. When developing a website or application, we often need to use APIs to obtain specific types of data. This article will introduce how to use PHP to connect to Baidu Wenxin Yiyan API to obtain data of specific types of sentences, and sort and paginate the data.

1. Register a Baidu developer account and create an application

Before using the Baidu Wenxin Yiyan API, we need to register a Baidu developer account and create one on the Baidu developer platform application. After creating the application, we can obtain the API Key and Secret Key of the application, which will be used in the subsequent code.

2. Connect to Wenxin Yiyan API and send a request

Using PHP to connect to Baidu Wenxin Yiyan API can be achieved through the cURL library. We need to set the request URL and parameters in the code, and specify the request header information, then send the request and get the returned data.

<?php
$url = 'http://api.xxxxxx.com/xxx/xxx'; // 替换成你的API请求URL
$apikey = 'xxxxxxxxxxxxx'; // 替换成你的API Key

$data = array(
    'type' => '类型参数', // 替换成你要获取的类型参数，例如：famous
    'num' => '获取数量', // 替换成你要获取的句子数量，例如：10
);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json', 'apikey:'.$apikey));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$response = curl_exec($ch);
curl_close($ch);

$result = json_decode($response, true);
if ($result && $result['status'] == 0) {
    $sentences = $result['result'];
    // 处理返回的句子数据
} else {
    echo '请求失败';
}
?>

In the code, we need to replace $url with your API request URL and $apikey with your API Key. The type parameter in the $data array can be set according to the type parameters provided in the Baidu Wenxin Yiyan API document. The num parameter is the number of sentences to be obtained. .

3. Sort and page the data

After obtaining the data, we can sort and page the data for display on the web page.

For data sorting, we can use PHP's usort() function to achieve it. This function sorts an array based on a specified comparison function. The following is an example:

<?php
// 对句子数据按照ID进行升序排序
usort($sentences, function($a, $b) {
    return $a['id'] - $b['id'];
});

For paging processing of data, we can use PHP's array sharding function to achieve it. The following is an example:

<?php
$page = isset($_GET['page']) ? $_GET['page'] : 1; // 获取当前页码
$pageSize = 10; // 每页显示的句子数量

$start = ($page - 1) * $pageSize; // 计算起始位置
$result = array_slice($sentences, $start, $pageSize); // 分片获取数据

// 在网页上展示分页数据
foreach ($result as $sentence) {
    echo $sentence['content'] . '<br>';
}

// 输出分页链接
$totalPage = ceil(count($sentences) / $pageSize); // 总页数
for ($i = 1; $i <= $totalPage; $i++) {
    $active = $i == $page ? 'active' : ''; // 当前页添加active类名
    echo "<a href='?page={$i}' class='{$active}'>{$i}</a> ";
}
?>

In the above code, we first get the current page number and calculate the starting position based on the number of sentences displayed on each page. Then use the array_slice() function to get the sliced ​​data. Finally, the paging data is displayed on the web page and the paging link is output.
