Ok, I think my example was a little too simplistic...
You could of course create multiple catch blocks and test for various errors.
In this simple example the catch might loook like
catch(Exception $e){
echo 'Uh oh: '. $e-getMessage();
}
This would tell you what the problem is perhaps.
Kind regards

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 /';
}

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.

[PHP] Am I supposed to be using SPL?
I was about to write code to recursively list the contents of a
directory when I remembered seeing an object in SPL that would do it for me:
http://us3.php.net/manual/en/function.recursivedirectoryiterator-next.php
But there is no documentation on this object, and although I have it in
PHP 5.1.4, docs say it's might be only in CVS. So, I try using it and
get this:
?php
$dir = new RecursiveDirectoryIterator(/some/dir/path);
while($dir-valid()) {
print $dir-current().\n;
$dir-next();
}
?
But it doesn't seem to recurse through the directories. In fact, this
acts just like DirectoryIterator. So, there must be a flag to make it
recurse, but documentation is not there. I see this documentation here:
http://www.php.net/~helly/php/ext/spl/
But that just looks like the source code was parsed to generate it,
nothing much help in seeing an example of the usage.

try looking at the userland version of the SPL classes they give quite abit
away as to how they work and how you can use them.

yes it's meant to be used, yes you can use it in production BUT your
a little on the bleeding edge (not very many people using it full on) AND
the whole of SPL is still a little in flex (as is php5-php6 in general) so
that you may be forced, occasionally, to adapt your code to changes (e.g.
constants that were formally used in SPL are now class constants.)
and please note this is not the official word but jmho.

Wow, this is some magical stuff. Here is my function in case it's of use:
//--
/**
* Magical SPL code to recursively list files in a directory
*/
public static function get_paths_recursive($start_path) {
$paths = array();
$rdi = new RecursiveDirectoryIterator($start_path);
foreach (new RecursiveIteratorIterator($rdi) as $path) {
array_push($paths, (string) $path);
}
return $paths;
}
//--
This iterates over objects like arrays, casts objects as strings, and
iterates
iterators. All sorts of fun and joy enough to make your head spin.
Seems to
work, though ;-)
Thanks for the wiki doc link, Jochem.
