I'm having a problem with exec on my hosting server. Unfortunately,
the hosting support seems to be anything but helpful.
The following works fine on my localhost:
<?php
$MaskData = "mask.exe -e \"TestString\"" ;
$Result = exec($MaskData, $Output, $ReturnValue);
echo("Result: ".$Result);
echo("ReturnVal ue: ".$ReturnValue. "<br/>");
foreach($Output as $outputline)
{
echo("outputlin e: $outputline<br> ");
}
?>
But on my hosting server, I've installed (I believe) the properly
compiled version for that os, and it always returns 127. I don't have
shell access, so I'm a bit of loss on how to proceed. Any
information on this return code or how to work through this, would be
greatly appreciated.
Thanks, J 7 2200

Hi J,
If you cannot execute in a shell, do a phpinfo(), and find the following
settings:
safe_mode = On or Off
and
safe_mode_exec_ dir =
Is safe_mode maybe On, and is your mask.exe not listed in
safe_mode_exec_ dir?
If so, you know why you cannot execute mask.exe.
Read more here: http://nl3.php.net/manual/en/function.phpinfo.php
Bottomline: Talk with your hosting provider. If they do not cooperate,
switch hosting provider or do not use mask.exe.

Hi Erwin,
Thanks for the quick reply. safe mode is actually off. This
application is in the same directory as the scripts. If I change
$MaskData = "mask.exe -e \"TestString\"" ; to $MaskData = "./mask.exe -
e \"TestString\"" ; (the addition of ./) the value of $ReturnValue is 1
and no values for $Result and $output. (Output should be a long
string).
A hosting provider switch is likely, but this is an immediate issue
that I need to get taken care. Once again, any help is much
appreciated.
Thanks, J

Good.

e \"TestString\"" ; (the addition of ./) the value of $ReturnValue is 1

string).
Ok, the $ReturnValue says 1, so I expect that the command DID run
succesfully.
Very strange your $Output array is empty.
Of course, what you want now is run the command by hand in a shell as
user PHP, being on Apache: Apache, or nobody or www-data, or
IUSR_<machinena meon IIS.
But you cannot.
So you'll have to debug by guessing.
Does the mask.exe has execution rights for PHP-user?
Do you maybe use files in mask.exe that are not accecible by PHP?
Throw in a full path to mask.exe instead of ./
Check your slashes, etc.
Try passthru() instead of exec().
And last but not least, insult the supportdepartme nt of your hosting
provider. ;-)
Good luck.

Well, passthru() should do this.
<quote>
The passthru() function is similar to the exec() function in that it
executes a command . This function should be used in place of exec() or
system() when the output from the Unix command is binary data which
needs to be passed directly back to the browser. A common use for this
is to execute something like the pbmplus utilities that can output an
image stream directly. By setting the Content-type to image/gif and then
calling a pbmplus program to output a gif, you can create PHP scripts
that output images directly.

Sorry James,
What you really need to do first is run the program from commandline to
see if it actually works.
You don't know for sure the program works. Is that right?
But I understand that is not possible, since you don't have shell. :-/
I think I would try the supportdepartme nt and ask then to try it for you.
Give them the command and ask them to run it for you.
If they refuse, shoot them. :P
It is very difficult to debug like this of course.
Sorry, I am also out of options.

What if you tried using exec to run the command but piping standard
out to one file and standard error to another file. Make sure both of
these files are in your home directory - and then use fopen to read
them. This probably won't help tooooo much but it might give you some
insight. Good luck!

As it turns out, after blindly switching binaries, I found out I was
trying to use a binary for a different OS. (too many flavors of unix)
Of course, if I had shell access, I could have found this out in 5
