【问题描述】：
我正在尝试为一家轮胎公司的客户列表构建代码。我已经完成了所有工作，但我仍然需要一个函数来更新单个客户并回显一个字符串，其中包含 .txt 文件中每个帖子的特定 ID。这是我所有的代码，因为当我尝试从数组中写出每个 id 时，我得到了这个：
无法将 Customer 类的对象转换为 /Applications/MAMP/htdocs/douglas/classes_serialisering.php 第 51 行中的字符串
这是我使用的代码 $key(".$obj
") 。 ....
这是程序的所有代码：
首先：classes_serialisering.php
<?php
//
// Registrera alla klassfiler som behövs.
spl_autoload_register(function ($class) {
include 'classes/' . $class . '.class.php';
});
global $company;
$company = new Company("Ragnars Däckhotell");
//
// Lägg till lagerpost i textfilen
if(isset($_REQUEST["addPart"])){
if(strlen($_REQUEST["customername"])>0){
$company->addCustomer($_REQUEST["customername"], $_REQUEST["customertfn"], $_REQUEST["customerepost"], $_REQUEST["tirebrand"], $_REQUEST["status"]);
//
//Spara information till filen med lagerinformationen.
file_put_contents("../objdata.txt",serialize($company- >getCustomerList()));
}
unset($_REQUEST["addPart"]);
header("Location: classes_serialisering.php");
exit();
}
//
// Radera en post i lagerregistret
if(isset($_REQUEST["delPart"])){
$company->removeCustomer($_REQUEST["delPart"]);
//
// Spara all ny information till textfilen med lagerinfon.
file_put_contents("../objdata.txt",serialize($company- >getCustomerList()));
unset($_REQUEST["delPart"]); // Disable button press
header("Location: classes_serialisering.php");
exit();
}
?>

关于为什么不能回显每个 id 的任何想法？而且，我应该如何制作一个功能，以便在填写表格后通过每个帖子右侧的按钮更新每个帖子，然后按“更新”，就像我现在拥有的“Radera”按钮一样，即“删除”在瑞典语中。
【问题讨论】：
-
你真的是想回显
$obj吗？它似乎是一个对象。 -
因为我像这样分配数组中的每个帖子，是的。 foreach($company->getCustomerList() as $key => $obj)
