[SOLVED] $_POST - using PHP and Flash

[learntoreed]

I've created a newsletter signup form using Flash.  The users include their email in a form with a variable name 'newsletter'.  Once they hit 'submit' the variable is sent to the following PHP file:

 

<?php
$fn = "newsletter.txt";
$file = fopen($fn, "a");
$size = filesize($fn);

if($_POST['newsletter']) fwrite($file, $_POST['newsletter']);

$text = fread($file, $size);
fclose($file);
?>

 

This writes the email addresses to the 'newsletter.txt' file.  What I can't seem to figure out is how to include a line break after the email is written to the file.  Right now all of the information submitted runs together in a single line. 

 

I've tried inserting '\n' in a number of places, but with no luck.

 

Any help would be greatly appreciated!

 

Thank you!

if($_POST['newsletter']) fwrite($file, $_POST['newsletter']."\n");

 

Also you might want to get the size of the file AFTER you write to it.

It is bad practice to only succeed with a newline character, also use a carriage return for compatability with all systems:

 

if($_POST['newsletter']) fwrite($file, $_POST['newsletter']."\r\n");

Works like a charm.  Thanks so much for your help!
