Answer 1

The 'advantage' of the database version is that no one can view the data. If neccesary, you can avoid access to the file by using a .htaccess file:

For apache 2.2

# Protect log.txt
<Files ./inscription/log.txt>
Order Allow,Deny
Deny from all
</Files>

For apache 2.4

# Protect log.txt
<Files ./inscription/log.txt>
Require all denied
</Files>

Answer 2

<?php
$file = fopen("ip.txt","a");
$ip=$_SERVER['REMOTE_ADDR'];
echo fwrite($file,$ip);
fclose($file);
?> 

Look at the manual

Check what the 2nd parameter means.

Youve chosen w mode which is an overrwrite mode. Try a mode instead (append)

Answer 3

Change "w" to "a"

W means write (over), a means append.
