php - 如何更正此 php 代码，以便在不生成错误代码的情况下发送电子邮件

Question

我正在尝试创建一个 HTML 表单，能够将包含工作申请信息的电子邮件发送到我的电子邮件地址，以便我可以回复潜在的申请人。我将提供表单代码以及 PHP 代码，当我单击提交按钮时，我希望将一封包含用户输入信息的电子邮件发送到电子邮件地址，但是我收到了错误消息，但我相信我已经检查过了对于最常见的错误，这些都没有出现，所以我猜我的代码中存在某种逻辑错误：

这是表单代码：

<div class = "form-group purple">
                    <form name = "applyhere" method = "post" action = "jobs.php">
                        <label for = "fullname">Enter Name Here:</label>
