Description:
------------
I'm not sure it's really a bug but did not find any explanation or on the web or php page.. here I go ..

I run the same script with different slashes and got 2 results

Test script:
---------------
$output = `C:\\WINDOWS\\system32\\cmd.exe /?`;
echo "<pre>$output</pre>";
...............................
$output = `C:/WINDOWS/system32/cmd.exe /?`;
echo "<pre>$output</pre>";


Expected result:
----------------
CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
    [[/S] [/C | /K] cadena]

/C      Ejecuta el comando especificado en cadena y luego finaliza
/K      Ejecuta el comando especificado en cadena pero sigue activo
/S      Modifica el tratamiento de cadena despu�s de /C o /K (consultar
        m�s abajo)
/Q      Deshabilita el eco
/D      Deshabilita le ejecuci�n de los comandos de AutoRun del registro 
        (consultar m�s abajo)
...........................................ETC

Actual result:
--------------
1 example return:

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
    [[/S] [/C | /K] cadena]

/C      Ejecuta el comando especificado en cadena y luego finaliza
/K      Ejecuta el comando especificado en cadena pero sigue activo
/S      Modifica el tratamiento de cadena despu�s de /C o /K (consultar
        m�s abajo)
/Q      Deshabilita el eco
/D      Deshabilita le ejecuci�n de los comandos de AutoRun del registro 
        (consultar m�s abajo)
...............................

2 example return this:

MKDIR [unidad:]ruta
MD [unidad:]ruta

Si las extensiones de comandos est�n habilitadas, MKDIR cambia as�:

MKDIR crea cualquier directorio intermedio de la ruta de acceso siempre 
que sea necesario. Por ejemplo, si \a no existe:

    mkdir \a\b\c\d

es lo mismo que:

    mkdir \a
    chdir \a
    mkdir b
    chdir b
    mkdir c
    chdir c
    mkdir d

That's just a curios behavior of "cmd.exe" if it's executed with forward slashs (just try it in the shell).

Hi valentiny510,

Did you try Carsten's suggestion of just trying it in the shell? It doesn't sound like it's an issue with PHP.
