I've tested this one. It works for me.

function getlast($filename,$linenum_to_read,$linelength){

   // this function takes 3 arguments;


   if (!$linelength){ $linelength = 600;}
$f = fopen($filename, 'r');
$linenum = filesize($filename)/$linelength;

    for ($i=1; $i<=($linenum-$linenum_to_read);$i++) {
    $data = fread($f,$linelength);
    }
echo "
";       
    for ($j=1; $j<=$linenum_to_read+1;$j++) {
    echo fread($f,$linelength);
    }

echo "
The filesize is:".filesize("$filename");
}

getlast("file.txt",6,230);
