如何使用带有文件作为源的php发送电子邮件

Question

This has already been answered here, but the result of the email is just a plain text version of the html.

I have a file called email.html.

This is the code I've used:

 <?php
if (!isset($_POST["submit"]))
  {
  ?>
  <form>
  <input class="button" type="submit" name="submit" value="Submit">
  </form>
  <?php 
  }
else
  {
  if (isset($_POST["from"]))
    {

    $email_text = file_get_contents('template.html');
    $headers = "From:[e-mail]";
    mail('[e-mail]', 'Hi', $email_text, $headers);
    }
  }
?>

You need to add the text/html Content-Type header to your email.

$headers = "From: [e-mail]";
$headers.= "
Content-Type: text/html";
