PHP提交到txt文件

Question

I have a subscribe option on my page. All I want is for users to be able to subscribe via email and have their emails save to a .txt file.

Here is my HTML form code:

<form action="contacts.php" method="post">
 E-mail: <input type="text" name="email" placeholder="Subscribe to our page for the latest News & Updates">
 <input type="submit" value="Subscribe">
</form>

I just need to know the script to write in the contacts.php file to save the emails.

I'm using XAMPP as a local server.

Answer 1

Your Form

<form action="contacts.php" method="post">
<input type="text" name="email" placeholder="Subscribe to our page for the latest News & Updates" />
<input type="submit" value="Subscribe" />
</form>

Use this code in your contacts.php

 $email = $_POST['email'];
 file_put_contents('emails.txt', $email . PHP_EOL , FILE_APPEND | LOCK_EX);
