PHP开发中如何实现百度文心一言随机语句的语义分析和情感评估？

<?php

// 设置百度AI开放平台的API Key和Secret Key
$apiKey = 'your_api_key';
$secretKey = 'your_secret_key';

// 要分析的语句
$text = '百度是一家全球领先的人工智能公司，致力于让“人工智能成为每个人的基本权利”。';

// 获取Access Token
$authUrl = 'https://aip.baidubce.com/oauth/2.0/token';
$authParams = array(
    'grant_type' => 'client_credentials',
    'client_id' => $apiKey,
    'client_secret' => $secretKey
);
$authResponse = file_get_contents($authUrl . '?' . http_build_query($authParams));
$accessToken = json_decode($authResponse)->access_token;

// 调用百度文心一言接口进行语义分析
$nlpUrl = 'https://aip.baidubce.com/rpc/2.0/nlp/v1/sentiment_classify';
$nlpParams = array(
    'text' => $text
);
$nlpHeaders = array(
    'Content-Type: application/json',
    'Charset: UTF-8',
    'Authorization: Bearer ' . $accessToken
);
$nlpOptions = array(
    'http' => array(
        'method' => 'POST',
        'header' => implode("
", $nlpHeaders),
        'content' => json_encode($nlpParams)
    )
);
$nlpResponse = file_get_contents($nlpUrl, false, stream_context_create($nlpOptions));
$nlpResult = json_decode($nlpResponse);

// 输出语义分析结果
echo '积极性：' . $nlpResult->items[0]->positive_prob . "
";
echo '消极性：' . $nlpResult->items[0]->negative_prob . "
";
echo '情感倾向：' . $nlpResult->items[0]->sentiment . "
";
