Help with PHP - dynamic signature script

[Steve Scrimpshire]

I posted this:

 

http://mandrakeusers.org/viewtopic.php?t=2...namic+signature

 

when I was running 8.1, now I'm running 9.1 and this script does not work. It just gives me:

 

"The image http://squirrelmessiah.no-ip/signature.png could not be displayed because it contains errors"

 

Any ideas? Here's the script again:

<?php

header ("Content-type: image/png");

Header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0");

Header("Expires: Thu, 19 Nov 1981 08:52:00 GMT");

Header("Pragma: no-cache");

$ut = strtok( exec("uptime"), "." );

$days = sprintf( "%2d", ($ut/(3600*24)) );

$hours = sprintf( "%2d", ( ($ut % (3600*24))/3600) );

$min = sprintf( "%2d", ($ut % (3600*24) % 3600)/60 );

$days = trim($days);

$hours= trim($hours);

$min = trim($min);



$img = @ImageCreate(245,60);



$recorduptime= "uptimebest";

$fp2 = isset($fp2) ? $fp2 : fopen("$recorduptime",'r');

$fp2=fopen("$recorduptime",'r');

flock ($fp2,1);

$best= fread ($fp2, filesize ($recorduptime));

flock($fp2,3);

fclose($fp2);

$record = explode("|",$best);



if ($days > $record[0]){

$fp2=fopen("$recorduptime",'w');

flock ($fp2,2);

fwrite($fp2,"$days|$hours|$min");

flock($fp2,3);

fclose($fp2);

}

if ($days == $record[0]){

if ($hours > $record[1]){

$fp2=fopen("$recorduptime",'w');

flock ($fp2,2);

fwrite($fp2,"$days|$hours|$min");

flock($fp2,3);

fclose($fp2);

}

if ($hours == $record[1]){

if ($min >= $record[2]){

$fp2=fopen("$recorduptime",'w');

flock ($fp2,2);

fwrite($fp2,"$days|$hours|$min");

flock($fp2,3);

fclose($fp2);

}

}

}



$fp2=fopen("$recorduptime",'r');

flock ($fp2,1);

$best= fread ($fp2, filesize ($recorduptime));

flock($fp2,3);

fclose($fp2);

$record = explode("|",$best);





$bg = ImageColorAllocate($img, 211, 211, 211);

$text_color = ImageColorAllocate ($img, 0, 0, 0);

$title_color = ImageColorAllocate ($img, 0, 0, 205);

ImageString($img, 3, 3, 1, "Last Reboot of My Linux Box: ", $title_color);

ImageString($img, 3, 3, 15, "$days days, $hours hours, $min minutes ago", $text_color);

ImageString($img, 3, 3, 29, "Record Uptime:", $title_color);

ImageString($img, 3, 3, 43, "$record[0] days, $record[1] hours, $record[2] minutes", $text_color);

ImagePNG($img);

ImageDestroy($img);

?>

 

TIA

 

Edit: Never mind. I didn't have all the php stuff installed. Carry on. ;)
