一、什么是企业三要素？

企业三要素即传入的企业名称、法人名称、社会统一信用代码或注册号，校验此三项是否一致。

二、具体怎么样通过PHP实现接口调用？

下面我们以阿里云为例，通过PHP示例代码进行调用，参考如下：

接口地址：https://market.aliyun.com/apimarket/detail/cmapi00068871?#sku=yuncode6287100001<?php$host = "https://kzcpthree.market.alicloudapi.com";$path = "/company_three/check";$method = "POST";$appcode = "你自己的AppCode";$headers = array();array_push($headers, "Authorization:APPCODE " . $appcode);//根据API的要求，定义相对应的Content-Typearray_push($headers, "Content-Type".":"."application/x-www-form-urlencoded; charset=UTF-8");$querys = "";$bodys = "creditCode=creditCode&companyName=companyName&legalPerson=legalPerson";$url = $host . $path;$curl = curl_init();curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);curl_setopt($curl, CURLOPT_URL, $url);curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);curl_setopt($curl, CURLOPT_FAILONERROR, false);curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);curl_setopt($curl, CURLOPT_HEADER, true);if (1 == strpos("$".$host, "https://")){curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);}curl_setopt($curl, CURLOPT_POSTFIELDS, $bodys);var_dump(curl_exec($curl));
?>

正确返回示例代码如下：

{"msg": "成功","success": true,"code": 200,"data": {"result": 2, //1一致，2不一致"orderNo": "202412012048184836138","companyName": true,   //true 正确， false 错误"legalPerson": false,"creditNo": true}
}
