    Handling include() warnings

    I'm new to PHP and trying to get a handle on some basics.

    require() and include() both load up a file. require() exits if the
    inclusion fails while include() issues a warning and the script
    continues. In the latter situation how should I detect the failure?

    include('Foo.ph p');

    if (...) {
    Foo::do_somethi ng();
    } else {
    backup_action() ;
    }

    What should the test be? Can I catch the warning thrown by the
    include()? Should I search through get_included_fi les()? The
    file being included is a "standard" one which might be missing from an
    installation, so I can't edit it to define a constant in it.

                      you might want to suppress the error generated by the failed include... and
                      maybe display some useful info... or maybe not.

                      if (!@include('Foo .php')) {
                      exit('Error in file: ' . __FILE__ . ' on line: ' . __LINE__);
                      }

                              Thanks for all the replies, even if they were from only 2 people ;-)

                              My requirement is to to use a module if it is available, otherwise
                              work round it. So using @ to suppress warnings is appropriate.

                              $foo_available = @include('Foo.p hp');

                              if ($foo_available ) {
                              Foo::do_somethi ng();
                              } else {
                              backup_action() ;
                              }
