Re: Using Optional Dependencies... ???

Having been caught by this quite a few times - code not working as expected because of optional dependancies.. I now kind of like the idea of if ($options['use_some_package']) {

     require_once 'The/Package.php';
     ......

} Making it fail bad and hard due to a missing dependancy that you explicity ask to be included.... Seems a suitable result.. otherwise - using include_once without the @ and letting the end user call your method with the @, forcing them to silence it.... Regards Alan Jon Parise wrote:

I have a query about how exactly to code optional dependencies... I use this:

           @include_once 'XML/Beautifier.php';

           if (in_array('xml_beautifier',get_declared_classes())) {
               $beautifier = new XML_Beautifier;
               $code = trim($beautifier->formatString($code));
           }

I can think of no other way to do it...

You can also do it this way: if ((@include_once 'XML/Beautifier.php') !== false) {

       ...

}
