As PHP now uses another feature of cmd.exe, this allows all elements of the
command line (programs and parameters) to be quoted quite happily.
As such, this request is no longer needed.

Description:

Hello.
(I was required to pick a version, but that is not really relevant).
This issue extends from a bug/feature of the Windows command shell executable (cmd.exe) which only
allows a single set of double quotes to be used when being used with the /C option.
e.g.
<?php
// Fine
exec('"C:\Program Files\Some Dir\Some Program" C:\somefile.txt');
// Not fine
exec('"C:\Program Files\Some Dir\Some Program" "C:\some file with a space in the
name.txt"');
?>
You get an error which is the same at the command prompt.
These work (the parameter is useless).
C:\windows\system32\calc.exe 123
"C:\windows\system32\calc.exe" 123
C:\windows\system32\calc.exe "123"
"C:\windows\system32\calc.exe" "123"
cmd /c C:\windows\system32\calc.exe 123
cmd /c "C:\windows\system32\calc.exe" 123
cmd /c C:\windows\system32\calc.exe "123"
But this doesn't work at the command line.
cmd /c "C:\windows\system32\calc.exe" "123"
You get the error ...
'C:\windows\system32\calc.exe" "123' is not recognized as an internal or
external command, operable program or batch file.
So, whilst this isn't a PHP bug, PHP could certainly help get around the problem.
My proposal is to either extend the PHP function realpath() to allow for a boolean parameter to
indicate the short name is to be returned.
e.g.
string realpath ( string path [, boolean return_short_name] )
or to introduce 2 new functions
string shortname ( string longname )
string longname ( string shortname )
In addition, extending the SPL to have a getShortName() method.
To get the shortname within MS VC++, there is a function called GetShortPathName(). There is also
GetLongPathName().
References to these functions can be found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/getshortpathname.asp
and http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/getlongpathname.asp
DWORD GetShortPathName(
LPCTSTR lpszLongPath,
LPTSTR lpszShortPath,
DWORD cchBuffer
);
DWORD GetLongPathName(
LPCTSTR lpszShortPath,
LPTSTR lpszLongPath,
DWORD cchBuffer
);
With the shortname() function, a filename like ...
C:\Program Files\Microsoft SQL Server\80\Tools\Binn\osql.exe
would become ...
C:\PROGRA~1\MI6841~1\80\TOOLS\BINN\OSQL.EXE
The name supplied is system dependent. I have a LOT of directories in "C:\Program Files"
starting with Microsoft.

In terms of impact, making 2 new functions which are Windows only would probably be easier.
