API或循环中有什么问题？

所以我有这个函数来获取API响应。

以下是API返回响应的内容; 

<?xml version="1.0" encoding="UTF-8"?>
<Response type="1">
<ack>
    <ackstatus>OK</ackstatus>
    <ackreason></ackreason>
</ack>
<dataversion>1</dataversion>
<hitcount>13391</hitcount>
<shops>
    <spad>
                </spad>
    <basead>
        <shop>
            <id>KN0100060500216636</id>
            <priority>1</priority>
            <entryname>旭川職業能力開発促進センター</entryname>
            <telno>0166-48-2412</telno>
            <zipcode>079-8418</zipcode>
            <address>北海道旭川市永山８条２０丁目３−１</address>
            <latitude>157707796</latitude>
            <longitude>512803967</longitude>
            <imageurl></imageurl>
            <promoword></promoword>
            <coupon>0</coupon>
            <group>0</group>
            <searchnum>7214223</searchnum>
        </shop>
        <shop>
            <id>KN0100060500202256</id>
            <priority>1</priority>
            <entryname>旭川市立／嵐山小中学校</entryname>
            <telno>0166-61-1199</telno>
            <zipcode>070-8051</zipcode>
            <address>北海道旭川市江丹別町嵐山１４３</address>
            <latitude>157704475</latitude>
            <longitude>512195888</longitude>
            <imageurl></imageurl>
            <promoword></promoword>
            <coupon>0</coupon>
            <group>0</group>
            <searchnum>7214223</searchnum>
        </shop>
    </basead>
</shops>
</Response>

所以在我的函数中我必须获取一些细节，例如; id，entryname，以便我可以将它们用作参数来获取不同的API：

这是功能; （我把日志放进去，如果我运行脚本就会显示结果。）

public function getcompList($prefectureId,$industryId,$offset)
{
    $itpCompanies = $this->itpApi->getCompanies($prefectureId,$industryId,$offset);
    $hascompany = $this->itpApi->getReturnArray();

    log_message('debug','Company list fetched, returning...');

    return $hascompany;
}

public function getcompanyList($hascompany,$prefectureId,$offset,$industryId)
{
    foreach ( $hascompany['shops']['basead']['shop'] as $company ) {
        $companyId = $company['id'];
        $entryName = $company['entryname'];
        $priority = $company['priority'];
        $searchNum = $company['searchnum'];

        log_message('debug', 'Comp_List API: company_id = ' . print_r($companyId, true));
        log_message('debug', 'Comp_List API: company_name = ' . print_r($entryName, true));
        log_message('debug', 'Comp_List API: company_prio = ' . print_r($priority, true));
        log_message('debug', 'Comp_List API: company_searchno = ' . print_r($searchNum, true));

        log_message('debug', 'Company_List->Company_Detail:: Getting Company Detail...');
        $this->compModel->getDetail($prefectureId,$offset,$industryId,$companyId,$entryName,$priority,$searchNum);
    }

}

例如，在上面的API响应中，日志将显示; 

Company list fetched, returning...
Comp_List API: company_id = KN0100060500216636
Comp_List API: company_name = 旭川職業能力開発促進センター
Comp_List API: company_prio = 1
Comp_List API: company_searchno = 7214223
Company_List->Company_Detail:: Getting Company Detail...
Company Detail Inserted!
Comp_List API: company_id = KN0100060500202256
Comp_List API: company_name = 旭川市立／嵐山小中学校
Comp_List API: company_prio = 1
Comp_List API: company_searchno = 7214223
Company_List->Company_Detail:: Getting Company Detail...
Company Detail Inserted!

问题是当API响应仅返回1 <shop>时。它给了我这个; 

Comp_List API: company_id = K
Comp_List API: company_name = K
Comp_List API: company_prio = K
Comp_List API: company_searchno = K
Company_List->Company_Detail:: Getting Company Detail...

因为这个函数也在一个检查并获取API的循环中，结果会给我错误;重复查询等。

可能是API中的问题吗？或foreach函数中的getcompanyList循环？

我不确切地知道你为什么会遇到单个结果的问题，但是因为你提供了XML我使用它并制作了2个版本，一个有两个结果，一个有一个结果。我改变了你的循环，无论我使用哪个版本的XML，我都能获得数据。这是一个完整的例子：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
</head>
<body>

<?php

function logCompanyData( $shops )
{
    foreach ( $shops as $company )
    {
        $companyId = $company->id;
        $entryName = $company->entryname;
        $priority  = $company->priority;
        $searchNum = $company->searchnum;

        echo 'debug: Comp_List API: company_id = ' . $companyId . '<br />';
        echo 'debug: Comp_List API: company_name = ' . $entryName . '<br />';
        echo 'debug: Comp_List API: company_prio = ' . $priority . '<br />';
        echo 'debug: Comp_List API: company_searchno = ' . $searchNum . '<br />';
        echo 'debug: Company_List->Company_Detail:: Getting Company Detail...' . '<br /><br />';
    }
}
