简单教程：PHP如何对接百度表格文字识别接口？

<?php
  // 设置接口请求的URL
  $url = 'https://aip.baidubce.com/rest/2.0/solution/v1/form_ocr/request';

  // 设置请求头部信息
  $headers = array(
    'Content-Type: application/json',
  );

  // 设置接口请求参数
  $params = array(
    'image' => base64_encode(file_get_contents('your_image.jpg')),
    'is_sync' => 'true',
    'request_type' => 'excel',
  );

  // 设置百度开发者账号和API Key、Secret Key
  $client_id = 'your_api_key';
  $client_secret = 'your_secret_key';

  // 拼接access_token的请求URL
  $token_url = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id='.$client_id.'&client_secret='.$client_secret;

  // 获取access_token
  $access_token = json_decode(file_get_contents($token_url))->access_token;

  // 设置access_token的请求头部信息
  array_push($headers, 'Authorization: Bearer '.$access_token);

  // 发送HTTP请求
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
  $result = curl_exec($ch);
  curl_close($ch);

  // 解析接口返回结果
  $result_json = json_decode($result);
  if ($result_json->error_code == 0) {
    // 请求成功
    $result_data = $result_json->result_data;
    // 处理返回结果
    // ...
  } else {
    // 请求失败
    echo '请求失败：'.$result_json->error_msg;
  }
?>
