Below is the print_r version of my array ($hamle). As you can see index(80) is empty or there is a end of line or a similar character there. I tried many options to delete it if it exists and is empty but couldn't do it. I strongly think that it is reading an empty line during the 'read while' loop. It doesn't appear in all files. It appears sometimes. Can anyone think of a chic way out?

The code =>
while(! feof($file))
{
$n=$n+1;
$hamle1= fgets($file);
$hamle1 = str_replace("
", "", $hamle1);
$hamle1 = str_replace("", "", $hamle1);
$hamle1 = trim($hamle1);
$hamle1 = explode(" ", $hamle1);
foreach($hamle1 as $item)
{
$hamle[] = $item;
}
