在这种情况下，
我的$to变量是否必须等于某些东西，或者我的函数会自动填充它。
<?php
if (isset($_POST["MainCB"])) {
$to = "test@test.com";
}
if (isset($_POST["ITCB"])) {
$to = "test@test.com";
}
if (isset($_POST["CateCB"])) {
$to = "test@test.com";
}
if (isset($_POST['submit'])) {
$full_name = $_POST['full_name'];
$MainCB = $_POST['MainCB'];
$ITCB = $_POST['ITCB'];
$CateCB = $_POST['CateCB'];
$subject = "Form submission";
$message = $full_name . " " . $MainCB . " " . $ITCB . " " . $CateCB;
mail($to, $subject, $message);
include 'mail.php';
}
?>

我建议阅读一些有关如何在 PHP 中发帖的文档，除此之外，您想完成什么？
if(isset($_POST["MainCB"]) || isset($_POST["ITCB"]) || isset($_POST["CateCB"])) {
$to = "test@test.com";
}
会做同样的事情，更if(isset($_POST['submit'])){应该永远等于真实，事实上这应该是你最外在的陈述。然后你用 '' 重写 $to 变量，所以在没有用例之前删除其他明智的代码。
是逻辑，阅读代码理解它并在需要时调整你的 if else 语句。
if(isset($_POST["MainCB"])){
$to[] = 'mycustomemail@address.com';
}
if(isset($_POST["ITCB"])){
$to[] = 'mycustomemail2@address.com';
}
if(isset($_POST["CateCB"])){
$to[] = 'mycustomemail3@address.com';
}
if(!empty($to)){
$to = array_unique($to); // remove duplicate entry's.
foreach($to as $address){
if(!filter_var($address, FILTER_VALIDATE_EMAIL)){
die("'$address' is not a valid email");
}
}
$to = implode(", ", $to);
} else {
die('No addresses to send the mail to!');
}
现在$to将拥有 1 个字符串中想要的所有地址，以便在mail()但是应该考虑使用 PHPMailer 等库，但首先关注编程的基础知识。
根据您在评论中所说的和这个问题： PHP 将邮件发送到多个电子邮件地址
您可以尝试像这样设置多个"to"：
<?php
$recipients = array();
if(isset($_POST["MainCB"])) {
$recipients[] = // one address email;
}
if(isset($_POST["ITCB"])) {
$recipients[] = // one other address email;
}
if(isset($_POST["CateCB"])) {
$recipients[] = // one more address email;
}
if(isset($_POST['submit']) && !empty($recipients) ){ // You need to have at least one email address to sent it
$to = implode(',', $recipients); // All your email address
$full_name = $_POST['full_name'];
$MainCB = $_POST['MainCB'];
$ITCB = $_POST['ITCB'];
$CateCB = $_POST['CateCB'];
$subject = "Form submission";
$message = $full_name . " " . $MainCB . " " . $ITCB . " " . $CateCB;
mail($to,$subject,$message);
include 'mail.php';
}
?>
这是你要找的吗？
if(isset($_POST["MainCB"])) {
$email = $email. ", example@logs.uk.com";
}
if(isset($_POST["ITCB"])) {
$email = $email. ", example@logs.uk.com";
}
if(isset($_POST["CateCB"])) {
$email = $email. ", example@logs.uk.com";
}
$mail = $_POST["Email"];
