The Edit PHP Executable window tries to save the php.ini when closed regardless of if changes were made. This prompts a warning on Ubuntu as the php.ini file and location are write protected.
Steps to reproduce:
1. Open PHP Interpreters options page (Preferences > Titanium > Editors > PHP > PHP Interpreters)
2. Edit an existing PHP Interpreter.
3. Click Ok.
As no changes were made to the php.ini no save should occur.
