Access command line via php (wordpress)

The problem is that the PATH environment used by our PHP setup does not include your ~/bin directory, so PHP cannot locate your locally-installed utilities.

You can work around it by setting the PATH as follows (replace "username" and "appname" with the appropriate values):

First, create /home/username/webapps/appname/set_path.php with the following contents:

1
2
3
4

<?php
  $_SERVER['PATH'] = '/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/username/bin';
  $_ENV['PATH'] = '/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/username/bin';
?>

Next, create /home/username/webapps/appname/php.ini with the following contents:

1

auto_prepend_file = "/home/username/webapps/appname/set_path.php"

Once that's done, PHP should be able to find your utilities and run them.

Hope that helps!
