Description:
------------
Using the scandir() method to fetch a list of filenames in a folder. Some filenames contain a space (via SSH this appears as "\ ", i.e. "test\ file.txt"). However PHP sees this file as "test_file.txt". This causes additional file operations such as file_exists() to return false.

Test script:
---------------
<?php
\\ path/to/folder/ contents:
\\ file.txt
\\ test\ file.txt

$scan = scandir('path/to/folder/');

foreach ($scan as $file)
{
    echo $file.'
';
}
?>

Expected result:
----------------
file.txt
test\ file.txt

Actual result:
--------------
file.txt
test_file.txt
