我正在使用以下代碼將 PHP 表單數(shù)據(jù)作為電子郵件發(fā)送。出于某種奇怪的原因，我只收到了 6 個(gè)字段的電子郵件，除此之外我沒有收到電子郵件。有人可以指出我做錯(cuò)了什么嗎？我現(xiàn)在使用$email郵件功能只是為了測試而不是使用實(shí)際的電子郵件。<?php  if(!empty($_POST["emailid"])) {     $name = $_POST["firstname"];     $middle = $_POST["middlename"];     $lastname = $_POST["lastname"];     $dob = $_POST["dob"];     $mobile = $_POST["mobileno"];     $whatsapp = $_POST["Whatsapp"];     $company = $_POST["companyname"];     $gender = $_POST["gendertype"];     $country = $_POST["country"];     $city = $_POST["city"];     $address = $_POST["address"];     $pincode = $_POST["post"];     $id = $_POST["idnumber"];     $adult = $_POST["adult"];     $children = $_POST["children"];     $roomtype = $_POST["roomtype"];     $in = $_POST["arrivate"];     $out = $_POST["tentative"];     $location = $_POST["location"];     $worklocation = $_POST["worklocation"];     $pickup = $_POST["pickup"];     $flight = $_POST["FlightNo"];     $intime = $_POST["ATime"];     $email = $_POST["emailid"];     $subject ="Reservations - New Booking ".$_POST["emailid"];     $toEmail = $_POST["emailid"];     //$mailHeaders = "From: " . $name . "<". $email .">\r\n";
