News script in flat file

[Dalibor]

I wrote some code for displaying news on my website.
Code goes like this:
<?
$newsfile = 'news.txt';
echo "<B>TRENUTN E VIJESTI</B><br>\n";
$data = file($newsfile) ;
$data = array_reverse($ data);
echo "<span style=\"normal 11 Verdana; color:#fff; text-align:justify;\ ">";
foreach($data as $element) {
$element = trim($element);
$pieces = explode("|", $element);
echo $pieces[2] . "<BR>" . "<span style=\"font:no rmal 11px
Tahoma\"><u>Pub lished</u>: " . $pieces[1] . " " . $pieces[0] .
"</span></span><BR><br>";
}
?>
I have form that puts content in flat file.

Messages are writen in flat file in format like this:
21.Feb 2006.|Dalibor|S ome message text
14.Feb 2006.|Dalibor|O ther message text...

I need piece of code for displaying last 5 messages and for deleting
certain messages.
Can you help me? Thanks!

Use array_slice to extract the last five messages. What constitutes a
"certain" message? Little hard to provide an example when we dont' know
what "certain" equals.

Well I ment to have admin page for news, in which will be diplayed all
messages, and after each message i want to be link for deleting that
message.
Like this:
Some message text
By Dalibor on 21.Feb 2006. - Delete
------------
Other message text...
By Dalibor on 14.Feb 2006. - Delete

And when I press delete message is deleted.

Re: News script in flat file

This code will delete your messages. It's coded for php5. If you're
running php4 then you'll have to substitute fopen, fwrite, and fclose
for file_put_conten ts.

shownews.php... .......
<?php
$data = file('news.txt' );
foreach ($data as $key => $value) {
print "$value: <a href=\"delnews. php?del=$key\"> delete</a><br
/>\n";
}
?>

delnews.php.... .........
<?php
$file = 'news.txt';
$data = file($file);
unset($data[$_GET['del']]);
print "<pre>";
print_r($data);
print "</pre>";
file_put_conten ts($file, $data);
?>
