【问题描述】：
我用 PHP 编写了一个 API，但我无法得到响应，之前我在另一个共享主机中使用了相同的 API，但是当我将服务器更改为另一个 go-daddy 共享主机时，一些 API 正在工作，但其他 API 没有.我不知道为什么会这样。使用邮递员，当我响应数组长度时，它得到正确的数组长度为 14（我的列数），但没有显示结果。请帮我解决问题
public function viewstock($token, $shopid)
{
$res = array();
$userId = $this->tokenVerification($token);
$delstatus = 0;
$ProductList = array();
$data = array();
if ($userId > 0) {
if ($stmt = $this->con->prepare("SELECT s.product_id,s.shop_id,s.product_category_id,s.display_order,s.sku,s.product_name,s.description,s.pro_type,s.is_timing,s.dateinfo,c.category_name,s.is_spe_offer,s.is_active FROM shop_stock s, category c WHERE s.product_category_id=c.id AND s.shop_id=?

$stmt->bind_param("ii", $shopid, $delstatus);
$stmt->execute();

这是一个不工作的 API，它使用 MYSQL 作为我的数据库。
当我使用 pirnt_r() 时，我可以得到回复，但为什么它没有显示在我的回复中
public function categorylist($token)
{
$res = array();
$userId = $this->tokenVerification($token);
$delstatus = 0;
$noparent = "None";
if ($userId > 0) {
$stmt = $this->con->prepare("SELECT p.id,p.category_name,p.display_order,p.dateinfo,IFNull((SELECT category_name from category WHERE p.parent_id=id),?)as parent,p.image FROM category p WHERE p.is_delete=? ORDER BY p.id DESC ");
$stmt->bind_param("si", $noparent, $delstatus);
$stmt->execute();
$stmt->bind_result($id, $category_name, $displayorder, $dateinfo, $parent, $image);
$CategoryList = array();
while ($stmt->fetch()) {
$temp = array();
$temp['category_id'] = $id;
$temp['main_name'] = $parent;
$temp['category_name'] = $category_name;
$temp['display_order'] = $displayorder;
$temp['dateinfo'] = $dateinfo;
$temp['image'] = $image;
array_push($CategoryList, $temp);
}
if (count($CategoryList) <= 0) {
$res['st'] = 'no';
$res['data'] = 'No Data';
} else {
$res['st'] = 'yes';
$res['data'] = $CategoryList;
}
/* free results */
$stmt->free_result();
/* close statement */
$stmt->close();
return $res;
} else if ($userId == 0) {
//token verification expired
//echo "Expired";
$res['st'] = 'expire';
$res['data'] = 'No Data';
return $res;
}
}
此代码正在运行并从同一服务器获取结果
【问题讨论】：
-
你需要
echo一些回应！这也是一个函数，所以你怎么调用它，显然你不能直接从 AJAX 调用中调用它 -
如果您查看 JOINing 表，您可以在一个查询中收集所有数据
-
我有另一个索引文件来调用这个函数，如果我给 echo "somevalue" 我可以打印；但不是回复
