Description:
------------
If you write a string to file with fputcsv that contains an even number of backslashes follwed by the enclosure character, you don't get your enclosure character back when you read it back in with fgetcsv().  Then you'll get an extra trailing enclosure character at the end of your string.

Reproduce code:
---------------
$tmp_file = '/tmp/csv_f_up.tmp';

$data_to_write = array('string contains even number of backslashes \\\\" followed by enclosure char');

echo "data_to_write:\n";
var_dump($data_to_write);

$h_w = fopen($tmp_file, 'w');
fputcsv($h_w, $data_to_write);
fclose($h_w);

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

echo "data_read_in:\n";
var_dump($data_read_in);

Expected result:
----------------
data_to_write:
array(1) {
  [0]=>
  string(73) "string contains even number of backslashes \\" followed by enclosure char"
}
data_read_in:
array(1) {
  [0]=>
  string(73) "string contains even number of backslashes \\" followed by enclosure char"
}

Actual result:
--------------
data_to_write:
array(1) {
  [0]=>
  string(73) "string contains even number of backslashes \\" followed by enclosure char"
}
data_read_in:
array(1) {
  [0]=>
  string(73) "string contains even number of backslashes \\ followed by enclosure char""
}

The same problem as #38918.

I confirm this with php 5.2.9 on windows:
$arr=array('\\','"');
$h=fopen('test.csv',"w");
fputcsv($h,$arr);
fclose($h);

$h=fopen('test.csv',"r");
$line=fgetcsv($h);
var_dump($line);

result:
array(1) {
  [0]=>
  string(6) "\",""
"
}
