<<prev next>> buttons using flat file

[Anon]

Ok I am currently working on a php admin script located here

http://216.118.121.28/snewznew/ -
not working yet as I am still working on the code

What I need is a code that reads the txt file and can store like an archive eg <<prev next>> at the bottom of every news subject.
One that I would prefer to use a flat file database??

Thanks

here is my basic code

if ($action == "addnews") {

$snewz_id = date("mdy")."-".date("gis")."-".date("B");
$date = "mdy"
$news_file_ok = "news.txt";

$new = "<div align=left>Review By $username: on $date<p><br> <a href='$sorurl'>$reviewheading</a><p>$reviewcontent</div><br>\n";

$f = fopen("$news_file_ok", "r");
$old = fread($f, filesize("$news_file_ok"));
fclose($f);

$new .= $old;

$f = fopen("$news_file_ok", "w");
fwrite($f, $new);
fclose($f);

$limit = 5;

$fcontents = "news.txt";

for($i=0; $i<$limit; $i++);

{ 

echo "<tr><td>"; 

echo "fwrite ($fcontents)[$i]"; 

echo "</tr></td>"; 

} 

}

//#################### Add Guides ####################//

if ($action == "addguide") {

$snewzlist_filename = "guides.txt";

$snewz_id = date("mdy")."-".date("gis")."-".date("B");

$news_file_ok = "guides.txt";

$new = "$username: $comment<br>\n";

$f = fopen("$news_file_ok", "r");

$old = fread($f, filesize("$news_file_ok"));

fclose($f);

$new .= $old;

$f = fopen("$news_file_ok", "w");

fwrite($f, $new);

fclose($f);

$limit = 5;

$fcontents = "guides.txt";

for($i=0; $i<$limit; $i++);

{ 

echo "<tr><td>"; 

echo "fwrite ($fcontents)[$i]"; 

echo "</tr></td>"; 

} 

}
