[SOLVED] LIMIT by 1

[Bricktop]

Hi all,

 

I have a bit of code which reads through the lines of a text file and outputs the result, the code is fine and is as follows:

 

function showprogress()
{ 	

$progressfile = text.txt;

$content = "";
  	foreach(file($progressfile) as $line)
  	{
    list($percentcomplete,$status) = explode("||", $line, 2);
$content .= '<div class="progressbar" style="width:'.$percentcomplete.'%">'.$percentcomplete.'%</div>';
$content .= '<div class="statusupdate">'.$status.'</div>';
}
echo $content;
}

 

What I would like to do is limit the output to only the last entry in the file, so instead of every line being output only the last line in the file is output.

 

Any ideas?

 

Thanks

After googling I found this answer:

 

$file = "/path/to/file";
$data = file($file);
$line = $data[count($data)-1];

 

Though, this WILL load the whole file into memory. Possibly a problem (or not). A better solution is this:

$file = escapeshellarg($file); // for the security concious (should be everyone!)
$line = `tail -n 1 $file`;

<?php
function showprogress()
{    
    $progressfile = "text.txt";
    $content = null;
    
    $arr = file($progressfile);
    $count = count($arr);
    
    list($percentcomplete, $status) = explode("||", $arr[$count], 2);
    
    $content .= '<div class="progressbar" style="width:'.$percentcomplete.'%">'.$percentcomplete.'%</div>';
    $content .= '<div class="statusupdate">'.$status.'</div>';
    
    echo $content;
}  
?>

Thanks guys, I can't get either to work, I'm not getting any values output.  here is what I have:

 

//This is the countdown.txt file, the countdown values are stored in this file
$progressfile = "text.txt";
$content = null;
    
    $arr = file($progressfile);
    $count = count($arr);
    
    list($percentcomplete, $status) = explode("||", $arr[$count], 2);
    
    $content .= '<div class="progressbar" style="width:'.$percentcomplete.'%">'.$percentcomplete.'%</div>';
    $content .= '<div class="statusupdate">'.$status.'</div>';
    
    echo $content;

I've worked it out, for anyone with a similar problem I used:

 

$lines = file("text.txt"); 
$last = sizeof($lines) - 1 ; 

    
    list($percentcomplete, $status) = explode("||", $lines[$last], 2);

 

Thanks.
