我正在尝试创建一个工作联系表单，但是当我提交表单时会显示此警告，警告：mail（）：无法连接到＆＃34; localhost＆＃34;端口25，验证您的＆＃34; SMTP＆＃34;和＆＃34; smtp_port＆＃34;在php.ini中设置或使用ini_set（）。我该如何解决这个问题？任何人都可以帮忙
主要代码在这里
<?php
if(empty($_POST) === false)
{
$errors = array();
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
if(empty($name) === true || empty($email) === true || empty($message) === true )
{
$errors[] = "Name, email and Message are required";
}
else if (filter_var($email, FILTER_VALIDATE_EMAIL) === false)
{
$errors[] = "This is not valid email address";
}
if (empty($errors)=== true)
{
$to = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" ;
mail($to, $subject, $message, $headers);
header('Location : index.php?sent');
exit();
