Below is the field where user enters his/her email address and the AJAX post request is sent to the server and the user sees the message:
[PHP]echo("<div id=\"message\" class=\"success\">Thank you! You have been successfully registered.</div>");[/PHP]
within 1.5 seconds.

<div class="subscribe">
<br />
Email Address: <input type="text" name="email1" id="email1" maxlength="36" size="36" />
<input type="button" name="go" value="Register" onclick="sendRequestPost(document.getElementById(' email1').value);" />
<div id="dt"></div>
</div>
</body>
[/PHP]</html>
This is subscribe.php:
[PHP]<?php
if(isset($_POST['email1'])){
$email = $_POST['email1'];
echo"<br>";
echo("<div id=\"message\" class=\"success\">Thank you! You have been successfully registered.</div>");
}
?>[/PHP]
Now my question is:
How to save text field data (i.e. the email address entered by the user) in a text file with multiple values separated by comma? Or in other case how to save these values in an Excel CSV file. We do not want these values to be stored in a database but just want a text file to be created on the first entered value and the rest of the values when entered second time or third time should be appended with the separation of comma i.e:
abc@abc.com,bbb@bbb.org.uk, ccccccccddd@efghi.com
and like that.
Can any one help?
