Description:
------------
when length is 0 function parse strange

notice "[0] =>  X" (there is space before X in actual result) - hexa is 0x00

simple when getting same line:
fgetcsv($fd, 0, ';') != fgetcsv($fd, 4096, ';')

Reproduce code:
---------------
FILE (contains only 1 line for example):
"X";"Y";"Zv";"Text";"H";"S";"R";"n";"I";"Ob";"P";"Roz";"Pdj"

<?php
$fd = fopen('file', 'r');

$t = fgetcsv($fd, 0, ';');

echo '<pre>';
var_dump($t);
echo '</pre>';
?>


Expected result:
----------------
array(13) {
  [0]=>
  string(1) "X"
  [1]=>
  string(1) "Y"
  [2]=>
  string(2) "Zv"
  [3]=>
  string(4) "Text"
  [4]=>
  string(1) "H"
  [5]=>
  string(1) "S"
  [6]=>
  string(1) "R"
  [7]=>
  string(1) "n"
  [8]=>
  string(1) "I"
  [9]=>
  string(2) "Ob"
  [10]=>
  string(1) "P"
  [11]=>
  string(3) "Roz"
  [12]=>
  string(3) "Pdj"
}

Actual result:
--------------
array(13) {
  [0]=>
  string(2) " X"
  [1]=>
  string(1) "Y"
  [2]=>
  string(2) "Zv"
  [3]=>
  string(4) "Text"
  [4]=>
  string(1) "H"
  [5]=>
  string(1) "S"
  [6]=>
  string(1) "R"
  [7]=>
  string(1) "n"
  [8]=>
  string(1) "I"
  [9]=>
  string(2) "Ob"
  [10]=>
  string(1) "P"
  [11]=>
  string(3) "Roz"
  [12]=>
  string(3) "Pdj"
}
