Thanks very much to both of you.
This does the trick! I had (stupidly) tried:
foreach ($c as new RecursiveIteratorIterator($item))
which with hindsight is completely illogical! I also wasn't aware of the
constants. Is there a simple tutorial / docs you know of for SPL?
not really, there are these 2:
http://www.php.net/~helly/
http://www.php.net/spl
and tutorials of (na)various quality ... and we have Nathan, who seems to
be well up to speed on SPL (IIRC he's tested and posted quite a bit about/with it)
I have
tried numerous google searches but the tutorials I have found assume I
already know what I am talking about (big mistake:-) ).
keep cross-referencing the info in different sources until something sticks. :-)
Even the PHP
docs are very sparse. A real shame, as the SPL seems fantastic and I
would love to use it more widely.
SPL has some very nice features, bare in mind that often the abstraction they
offer is a performance overhead ... but not always, for instance I found that
a 'new FilterIterator(new RecursiveDirectoryIterator())' was faster than using
glob() (well 2 calls to glob()) when the number of files exceeded around 300
(in the given directory structure).
One other thing... is there a mirror for this list? I'm sure SPL must
have been covered many times before, but every time I try to search, the
server times out.
plenty, where do you think the spammers grep your email addr from?
try http://marc.info/?l=php-general&r=1&w=2
...
/mode/ Operation mode (one of):
* LEAVES_ONLY only show leaves
* SELF_FIRST show parents prior to their childs
* CHILD_FIRST show all children prior to their parent
so, i typically use SELF_FIRST, and then Jochem's example would become,
..
foreach(new RecursiveIteratorIterator($c,
RecursiveIteratorIterator::SELF_FIRST) as $item)
good catch, wasn't aware of the mode argument, I've only ever played with
it in terms of directory iteration (where LEAVES_ONLY makes sense in the common
use case)
