...on $e) instead of catch(Exception $e) . If you are using a code you don't know about very well, or - especially - if you are using a framework, it might override the default PHP Exception with one of its own, and therefore you might go to the wrong path and get the undesired result.

Bootstrap control with multiple “data-toggle”
