exec() trouble

andrewpasetti

I"m having a bit of trouble with the exec command. Perhaps someone can suggest what I'm doing wrong. I know php has support for mcrypt, but I'm not able to recompile or upgrade my current version, so this is my only option.

When I execute this statment, no output is returned and the statement is not executed. I copied the command right from the command line after successfully executing it there.

Any suggestions?

Thanks,

Andrew

echo exec("mcrypt -u -f /usr/local/www/vhosts/easy411.com/crypt/keyfile.txt -a des /usr/local/www/vhosts/easy411.com/crypt/test.txt",$output);
echo $output;

foreach($output as $outputline){
echo("$outputline<br>");
}

Hello,

Can you please let me know what you are trying to do this? Possibly there is a different way?

There could be many problems to why this might not work correctly.

Possibly you’re PHP webserver is not allowed to run command on the system?
Or you do not have permission to run the command.
You might also have the path incorrect.
It is also possible that the executable is not allowed (via permissions) to execute.

There are many problems to this approach. Like I said above why are you trying to do this?

Thanks,
- Justin

Thanks for replying. I'm trying to do this because the server hosting this account will not allow me to reconfigure php to recognize the mcrypt functions.

I am allowed, however, to install programs. So that was my plan: to install mcrypt then use the exec command to interface with it instead of using the php functions.

Can you suggest where I can start trying to locate the problem. Or perhaps there's an easier method of doing this.

Your advice will be greatly appreciated,
