Description:
------------
Two issues when reading in data from a CSV with fgetcsv():

If an element in a CSV file begins with a newline, fgetcsv() will think there's two newlines there.

If an element in a CSV file ends with an odd number of trailing backslashes, it'll miss the enclosure character.

This isn't a documentation problem - http://www.rfc-editor.org/rfc/rfc4180.txt
Backslashes are not escape characters in CSV.

Reproduce code:
---------------
mikef@dev9:~$ cat -A /tmp/csv.tmp
"$
two seperate issues: string begins with a newline, ends with odd number of backslashes \\\","and isnt the last element"$

mikef@dev9:~$ cat test_cvs.php
<?php
$tmp_file = '/tmp/csv.tmp';

$h = fopen($tmp_file, 'r');
$data_read_in = fgetcsv($h);
fclose($h);

var_dump($data_read_in);
?>

Expected result:
----------------
mikef@dev9:~$ php test_cvs.php
array(2) {
  [0]=>
  string(92) "
two seperate issues: string begins with a newline, ends with odd number of backslasshes \\\"
  [1]=>
  string(25) "and isnt the last element"
}

Actual result:
--------------
mikef@dev9:~$ php test_cvs.php
array(1) {
  [0]=>
  string(121) "

two seperate issues: string begins with a newline, ends with odd number of backslashes \\\",and isnt the last element""
}
