Sort news from latest to the oldest

[Ollifi]

Hello,

 

I have a PHP news script which I have coded myself.

Everytime when I want to show all the news I´ll first use function array_reverse for the news textfile array.

But, when I add a new news in the file, the news ID changes.

 

Line numbers: <x>

 

So example the textfile:

<0>First message
<1>Second message
<2>Third message

When I add the new news:

<0>First message
<1>Second message
<2>Third message
<3>Fourth message

 

And when I use array_reverse

<0>Fourth message
<1>Third message
<2>Second message
<3>First message

 

But I want that the "First message" always has ID number 0 etc. (line number is ID number)

 

How could I do so? Should I make some changes for the for function?

 

Thank you for help, hopefully you will understand my explaining

post some code so we can see what you are doing then we may be able to help with the issue

It might be worth reading about the preserve_keys parameter of the array_reverse function.

Thank you very much, I will try it!

Sorry, but it didn´t worked. Please have look whats wrong:

 

<?php
$filu = array_reverse(file("news.txt"), true);

for($i=0;$i<count($filu);$i++){
$exp = explode("|", $filu[$i]);
$pvm = str_replace("\n", "", $exp[3]);
print'<a href="read.php?a=read&id='.$i.'"><strong>'.$exp[0].'</strong></a> (<span class="day">'.$pvm.'</span>)';
print"<br>";
}
?>

 

And here is the news.txt file:

TITLE|LONGTEXT|SHORTTEXT|DATE
TITLE|LONGTEXT|SHORTTEXT|DATE

 

But now it shows the news from oldest to the latest.

 

And forgot to mention- the file is ordered from oldest to the latest (line0=oldest news,latest line=latest news)

<?php
$lines = array_reverse(file("news.txt",FILE_IGNORE_NEW_LINES), true);
foreach($lines as $key => $line){
list($title,$long_text,$short_text,$date) = explode("|", $line);
echo "<a href='read.php?a=read&id=$key'><strong>$title</strong></a> (<span class='day'>$date</span>)<br>\n";
}
?>

thank you for the script. Is it possible to do the same with for function?

[PFMaBiSmAd]

You would have your for(){} loop start with the highest key number and decrement it until it reaches zero.

Thank you for help. I tried with this code:

<?php
$filu = array_reverse(file("news.txt"));
$maara=count($filu)+1;
for($i=$maara;$i>0;$i--){
$exp = explode("|", $filu[$i]);
$pvm = str_replace("\n", "", $exp[3]);
print'<a href="read.php?a=read&id='.$i.'"><strong>'.$exp[0].'</strong></a> (<span class="day">'.$pvm.'</span>)';
print"<br>";
}
?>

 

But it only shows me the first line of the file. Others are just ().

<?php
$lines = file("news.txt",FILE_IGNORE_NEW_LINES);
for($i = count($lines) -1; $i >= 0; $i--){
list($title,$long_text,$short_text,$date) = explode("|", $lines[$i]);
echo "<a href='read.php?a=read&id=$i'><strong>$title</strong></a> (<span class='day'>$date</span>)<br>\n";
}
?>
