You are right, it's the php code. But I don't see anything wrong with the
following:

$x=0;
$ar=array();
$f = fopen ("../employee.txt", "r");
while (!feof ($f)) {
    $ar[$x] = fgets($f, 4096);
    $x++;
}

The count of $ar returns 4 even though there are actually 3 records. So I
am not sure if you would call it an expected behaviour.
