Comment by: dj-bj@gmx.net
Reported By: dj-bj@gmx.net
Status: Bogus
Bug Type: Program Execution
Operating System: Windows 2000 Server
PHP Version: 4.2.3
New Comment:
Thank you for the tip to add 2>&1 to the command. This prevents any
crashed output from beeing sent to the page (take >nul for no output).
The documentation says:
shell_exec -- Execute command via shell and return complete output as
string
and not
Execute command via shell and return complete output as string only if
exectued command is true but crash when false..
However, thank you for your assistance.
Regards,
Bj

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
If you want to recieve the error messages append '2>&1' to the end of
the command you are executing. This will work on any *nix based system
as well as most recent Win32 server oses such as Windows NT and Windows
2000.

I installed this version using the old ini file - no errors execpt the
one reported.
Still, the result of shell_exec is not passed to the variable but
displayed on the page with added "
Content-type: text/html
X-Powered-By: PHP/4.4.0-dev
" after the error message.
In my script i control some nt services and therefor i tell shell_exec
to execute net start / net stop. If a service has already been started
and i attempt to start it again it returns the error "More help is
available by typing NET HELPMSG 2182." like in DOS Shell on Windows but
this error not passed to the variable.

Running PHP 4.2.3 on Windows 2000 Server shell_exec works fine and
passes its output to the variable when the result of the executed
command is true.
However, if the command fails and the DOS-shell returns an error the
result is no longer availiable in the variable but is passed directly
to the page.
