消息没有发送联系表

我想创建一个联系表单，用户将填写他们的姓名，电子邮件，主题和消息以便与我联系。这是假设发送电子邮件到我的电子邮件帐户，但每次我测试它，它不起作用。我确信这是正确的，但我想不是。请帮忙吗？消息没有发送联系表

<?php 

//Get user input 
$name = $_POST["name"]; 
$email = $_POST["email"]; 
$subject = $_POST["subject"] 
$message = $_POST["message"]; 

//error messages 
$missingName = '<p><strong>Please enter your name!</strong></p>'; 
$missingEmail = '<p><strong>Please enter your email address!</strong></p>'; 
$invalidEmail = '<p><strong>Please enter a valid email address!</strong></p>'; 
$missingSubject = '<p><strong>Please enter a Subject!</strong></p>'; 
$missingMessage = '<p><strong>Please enter a message!</strong></p>'; 

//if the user has submitted the form 
if($_POST["submit"]){ 
    //check for errors 
    if(!$name){ 
     $errors .= $missingName; 
    }else{ 
     $name = filter_var($name,FILTER_SANITIZE_STRING); 
    } 
    if(!$email){ 
     $errors .= $missingEmail; 
    }else{ 
     $email = filter_var($email, FILTER_SANITIZE_EMAIL); 
     if(!filter_var($email,FILTER_VALIDATE_EMAIL)){
