email — PHP не отправляет почту при прикрепленном файле

Я искал через этот сайт, но я не могу найти что-то связанное с этим. Если есть, пожалуйста, покажи мне.

Мой php делится на две секции, одна отправляет почту, если вложения нет (работает нормально)

Далее следует прикрепить файл и отправить его вместе с ними $ msg. Это, однако, не работает. Я собираюсь включить полную отправку почты PHP здесь.

    <?php
error_reporting(-1);
ini_set('display_errors', 'on');

ini_set("SMTP", '\');
ini_set("smtp_port", "25");
ini_set('sendmail_from','noreply@edomain');
if($_POST)
{
$to_email       = "email here"; //Recipient email, Replace with own email here

$from_email     = "noreply@domain"; //From email address (eg: no-reply@YOUR-DOMAIN.com)

//check if its an ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
$output = json_encode(array( //create JSON data
'type'=>'error',
'text' => 'Sorry Request must be Ajax POST'
));
die($output); //exit script outputting json data
}

//Sanitize input data using PHP filter_var().
$user_name      = filter_var($_POST["user_name"], FILTER_SANITIZE_STRING);
$user_email     = filter_var($_POST["user_email"], FILTER_SANITIZE_EMAIL);

//additional php validation
if(strlen($user_name)<4){ // If length is less than 4 it will output JSON error.

die($output);

У меня есть идея, что это связано с $ FILES и $ POST, но я не могу сделать это правильно
