Flat log file

I'm currently wanting to learn about flat file databases so decided to make a flat file log.

I have the following code:

<?php
  $file = \"log.txt\";
  $filetr = fopen($file, \"r+\");
  $log_string = array(
    gethostbyname($_SERVER['HTTP_HOST']),
    date(\"F j Y\"),
    date(\"g:i A\"),
    $_SERVER['HTTP_REFERER'],
    $_SERVER['PHP_SELF'],
    $_SERVER['HTTP_USER_AGENT']
  );
  $data = implode(\"~\", $log_string);
  fwrite($filetr, $data);
  $filetr = fclose($filetr);
?>

I would like it to write to the beginning of the file pushing the next one down, however, it just overwrites.

Some help please?

I figured it out now, heres the code that I used:

<?php
  $file = \"log.txt\";
  $filetr = fopen($file, \"r+\");
  $data_old = fread($filetr, filesize($file));
  $filetr = fclose($filetr);
  $filetr = fopen($file, \"w+\");
  $log_string = array(
    gethostbyname($_SERVER['HTTP_HOST']),
    date(\"F j Y\"),
    date(\"g:i:s A\"),
    $_SERVER['HTTP_REFERER'],
    $_SERVER['PHP_SELF'],
    $_SERVER['HTTP_USER_AGENT']
  );
  $data_new = implode(\"~\", $log_string);
  $data = $data_new . \"\n\" . $data_old;
  fwrite($filetr, $data);
  $filetr = fclose($filetr);
?>

I'm using

<?php
gethostbyname($_SERVER['HTTP_HOST'])
?>

to get an IP but I realised that I was getting the IP of my host, how do I get the IP of the viewer of my site?

Quote: 'REMOTE_ADDR'
The IP address from which the user is viewing the current page.

'REMOTE_HOST'
The Host name from which the user is viewing the current page. The reverse dns lookup is based off the REMOTE_ADDR of the user.

Note: Your web server must be configured to create this variable. For example in Apache you'll need HostnameLookups On inside httpd.conf for it to exist. See also gethostbyaddr().
