Reasons for exec() failing

[rogair]

I have a script that generates a zip file from various other files. I've just migrated to a new server and this script won't work. Safe mode is off. The command from the exec() run on the command line works by itself, but it won't run within the script. What are other possible causes for an exec failing if the command within the exec is fine?

Thanks.

Could be a permissions thing try switching to the webserver user and run the command. Or maybe ther is more info in your error_log.

Thanks. I checked the logs (duh) and for some reason it wasn't finding the command. I put in the full path for the command and it worked. Question now is why does the path work on some scripts and not this one?

Try switching to the webserver user on my system that is nobody then type cd it should take you to the root directory for that user then have a look at the login profile for that user.
i.e.

su nobody
cd
cat .bash_profile

it should list the path in the profile if the command that you want is in the path specified then it will work if not it doesnt know where to look. You could always edit the profile to include the run path of the executable.

Mark.
