HTML into a text file using PHP - php

Question

I am trying to get this information into a text file using PHP.
All of the websites that I have looked at only really cover entering a first and a last name had having the information echoed.
I was wondering if anyone has a suggestion on how to do this? That would be very helpful.
<form action="action.php" method="post" />

This is fairly straightforward,
$file = "myfile.txt";
if (isset($_POST['question']) && isset($_POST['tool'])) {
$fh = fopen($file, 'a');
$text = $_POST['question']. ' ' .$_POST['tool'];
fwrite($fh,$text); // Write form data to the file
fclose($fh); // Close the file
}
This would be put in your action.php file, and would write to a file in the same directory.
Also a caveat, you have input names that aren't unique, so you would want to add a third field to this. 'question' should be a unique name as you're using it when posting data.
