Hi all,

I'm using the exec() command in PHP5 to run some Perl scripts external to my web application. I noticed that the environment variables are not always set properly in the shell created by exec(). For example, if I run the following PHP script through apache just to list the content of environment variables, I get these results:

<?php

exec("export", $output);
print "<pre>";
var_dump($output);
print "</pre>";

array(4) {
  [0]=>
  string(13) "export OLDPWD"
  [1]=>
  string(43) "export PATH="/usr/bin:/bin:/usr/sbin:/sbin""
  [2]=>
  string(41) "export PWD="/Library/WebServer/Documents""

  [3]=>
  string(16) "export SHLVL="1""
}

Some critical environment variables are missing such as TMPDIR and PERL5LIB and so on. I found a workaround, namely using the putenv() command at the beginning of my script, like this:

putenv("PATH={$_ENV["PATH"]}:$dir1:$dir2");
putenv("PERL5LIB=$dir3:$dir4");
putenv("TMPDIR=/private/tmp");

However, I'd like to set these variables once and for all in a profile somewhere and not have to deal with them in the script itself.

So my question is: where is that profile for the _www user (or any user running under apache)?
