add .php extension to a wrtten file

file name is a passed variable

[petra]

<?php
$File = $_POST['mysql_connect'];
$Handle = fopen($File, 'w');

$File is passed from an HTML form. Where do I define the extension of the file that is to be written?

Thanks!

Hi Petra,

Append it to $File?

$Handle = fopen($File.'.php', 'w');
