Paging text files...

[Anon]

Hi.
I use a text file as my database, for my news posting script, it works... but I was wondring can I page text files too? like 10 posts a page?

its a simple script, this is how the data is stored in the text file:

"title@~%post"
each line a new post, please can you help me...

Sincerely

your offset be, for example, 20 postings.
your starting point be 0.

on top of your script, read in the postings file using the file() function:
$postings = file("postings.txt");

now the file is in an array, 1 line = 1 posting.

at the first time (link from menu, ...) call the script with the parameters:
?start=0&offset=20

in the script, generate the posting list using:

for($i=$start; $i<$start+$offset; $i++)
{
// output of 1 posting
$parts = explode("@~%", trim($postings[$i]));
echo "Title: ".$parts[0]."<br><br>Posting: ".$parts[1]."<br><br>";
}

now place prev/next links:

<a href=thisscript.php?start=<?=($start-$offset) ?>&offset=<?=$offset ?>>previous <?=$offset ?></a>

<a href=thisscript.php?start=<?=($start+$offset) ?>&offset=<?=$offset ?>>next <?=$offset ?></a>

I hope you get the point ...
