form that saves information entered into a data.txt file php none of them works : <p>i'am looking for form that has index.html and process.php
In index you enter Your Name: 
Your age: (but you dont enter it gives you option from 10 to 50) and you click submit 
and that information saves in data.txt file on /var/www/html not on client side.
I've tried hundred of them none of them works</p>

<p>Also please don't link other forms i've tried hundred of them on stack, on google, look they are all outdated?
