Is SPL meant to be used? If so, is it experimental? Is it

Should I stay away from SPL for production code? What's the
official word?
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.
