Can I get the short DOS name of a file from PHP?

Question

I want to pass a file path as a parameter to an executable from PHP, and the file path may contain spaces. The executable doesn't seem to handle quotes around the parameter, so I thought maybe I could pass the short DOS name instead of the long name.

Does PHP know anything about the old-style DOS 8.3 file names?

Answer 1

php/win32 ships with the COM/.net extension built-in. You can use it to create a WSH FileSystemObject and then query the ShortPath property of the File object.

<?php
$objFSO = new COM("Scripting.FileSystemObject");
$objFile = $objFSO->GetFile(FILE);
echo "path: ", $objFile->Path, "\nshort path: ", $objFile->ShortPath;

prints e.g.

path: C:\Dokumente und Einstellungen\Volker\Desktop\test.php
short path: C:\DOKUME~1\Volker\Desktop\test.php

Answer 2

You may want to have a look at escapeshellarg() and put the parameter in between double quotes.

Answer 3

You want the GetShortPathName API in Kernel32 on windows. To call this from PHP, you will need to use the Win32 API extension...

Answer 4

How about backslashing the space?
