backtick operator not behaving?

[Anon]

I have a perl program I wrote that pulls data from a database and runs a bunch of programs via perl's backtick operator. It runs correctly if I su to the www user .. However, when i try to run it from php's backtick operator

$output = /home/bounce/testsend.pl;
echo "<pre>$output</pre><br>";

I get the output from the program printed, but it doesn't execute correctly. It's supposed to send emails, and while it does when run from the commandline, it doesn't when run in php's backticks. I made every path absolute in testsend.pl in case it was a problem of a program not being in the path.

Thanks in advance for any help

Try doing something like this:

passthru("perl /home/bounce/testsend.pl");

Hope it works for ya.

nope...passthru() doesn't solve the problem, nor does system() or exec()

i'm really stumped about this one..i guess it could be file permission related, but i made sure that everything dealing with this is owned by www

This may be an environment pb.
Environement vars may not be the same when you execute in a shell or executed via PHP.

if that is the case you can try putting the following before the exec(), passthru(), etc... command:

putenv("HOME=/home/www");
//as long as there is a directory there 😉

putenv("USER=www");
