Hi.

Im trying to make a shout box that displays posts in a gd image that i plan to use in my sig on my forum.

The problem i am having is the php script posts to the bottom of the .txt file.
This means after 6 posts any new posts are not visible because they have dissappeared off the bottom of the image.

To fix this problem i need to either make the php post the posts to the top of the text file (while moving other posts down, not overwriting) or make the script that produces the image read only the last 6 posts from the .txt file.
I dont know how to do either.

Any help would be great.

This is the script that posts the 'shouts' to the txt file.

PHP Code:

<?php 



$filename = "shouts.txt"; 





$shout = trim(strip_tags(stripslashes( $_POST['shout']))); 

$name = trim(stripslashes(strip_tags($_POST['name']))); 





$fp = fopen($filename,'a'); // 'a' will append or add to the file 

{ 

        fwrite($fp, "$name - $shout\n"); 

    } 

fclose($fp); 



?>

And this is the php that gets the text from the txt file and produces the image

PHP Code:

<?php 

// shout sig 

header("Content-type: image/png"); 

$file = file('shouts.txt'); 





$im = @imagecreate(550, 120) 

   or die("Error! Could not create image stream.s"); 

$background_color = imagecolorallocate($im, 0, 0, 0); 

$text_color = imagecolorallocate($im, 0, 255, 0); 

$i = 1; 

$j = 0; 

foreach ($file as $line_num => $line) { 

    if($i <= count($file)-1) 

        imagestring($im, 2, 5, $j,  substr($line, 0, strlen($line)-1), $text_color); 

    else 

        imagestring($im, 2, 5, $j,  $line, $text_color); 

    $j+=15; 

    $i++; 

} 

imagepng($im); 

imagedestroy($im); 

?>

Does anybody know what i would have to change in order to make the newest post appear at the top of the image?

note:
I have tried fopen($filename,'r+'); but it just overwrote the top entry meaning there was only ever 1 post on the text file.

thanks

Hi mdhall. That link looked like it would of fixed the problem.
However, i was told of a simple solution in the script that creates the image.

I replaced

PHP Code:

$file = file('shouts.txt'); 

With

PHP Code:

$file = array_reverse(file('shouts.txt'));
