Handling include() warnings

[Pete Forman]

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.php');

if (...) {
Foo::do_something();
} else {
backup_action();
}

What should the test be? Can I catch the warning thrown by the
include()? Should I search through get_included_files()? 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.php');

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