Description:
------------
fgetcsv() gives different output on php6 compared to php6 on linux.

Reproduce code:
---------------
<?php

$filename = dirname(__FILE__) . '/fgetcsv1.tmp';

$file_handle = fopen($filename, "w+" );
$delimiter = '\\';
$csv_field = 'water\\"fruit"\\"air"';

fwrite($file_handle, $csv_field . "\n");

rewind($file_handle);

var_dump( fgetcsv($file_handle, 1024, $delimiter ) );
// close the file
fclose($file_handle);
//delete file
unlink($filename);

?>


Expected result:
----------------
according to php5 the output is:

array(3) {
  [0]=>
  string(5) "water"
  [1]=>
  string(5) "fruit"
  [2]=>
  string(3) "air"
}


Actual result:
--------------
Output on php6 is:

array(1) {
  [0]=>
  string(19) "water\"fruit"\"air""
}
