Officially SPL is part of PHP. It provides a standard interface for iterating over aggregate objects, eg: array, directory listing, xml, etc... try{ foreach ( new DirectoryIterator('./') as $Item )

       {
       echo $Item.'<br />';
       }

} catch(Exception $e){ echo 'No files Found!<br />'; }

So, of all the things that COULD go wrong, we just assume it's "No files Found"??? I don't think I'll ever learn to like SPL or try/catch...

12 months ago you wouldn't be seen dead near an install of php5 ;-) on a more serious note Kevins uber simple try/catch block is not indicative of the crapness of exceptions per se - besides it's already better handling than most noobs have in there code (not to say that Kevin is a noob because I can't judge that based on just this - besides we were all noobs once) to give a pseudo example: try { // do stuff with DirectoryIterator } catch (SomeKindOfDirectoryIteratorRelatedException $e) { // empty dir? } catch (SomeOtherKindOfDirectoryIteratorRelatedException $e) { // file system permissions failure? } catch (YetAnotherKindOfDirectoryIteratorRelatedException $e) { // dir doesn't exist } catch (Exception $e) { // failsafe/fallback catch for when we don't have a clue what went wrong } <stupid_pun> so you could 'try' to like it, it will probably 'catch' on regardless </stupid_pun> better the devil you know.
