Summary: Missing interfaces
Initial Comment:
Hi,
I installed the PEL library and began to test it. I
wanted to use the getIterator function on a pelIfd
object but I got errors on the $tag object that should
have been issued. I walked through the code and
discovered that pelIfd.php was implementing interfaces
at line 73: IteratorAggregate and ArrayAccess.
I cannot find anywhere those interfaces...
Could you please help me?
Thanks

I'm using PHP 5.1.4 ...
When I make an iterator object with:
$ifd = $ifd0->getIterator();
and then loop through it with:
foreach ($ifd as $tag => $entry) {
echo($tag." : ".$entry->getText()."<br />\n");
}
$entry is considered like a PelEntry object but if I try to
get the name of $tag ($tagName = $tag->getName();) I get the
following error:
Fatal error: Call to a member function getName() on a
non-object in ...
As I understand, $tag should be a PelTag object, but when I
make a print_r($tag), I get only numbers (270, 271, 272,
274, 282,...)!?
Where could be the problem?
Thanks for your help...
Best regards.

They are part of the Standard PHP Library, SPL, please take
a look at http://www.php.net/~helly/php/ext/spl/.
But you shouldn't have to do anything, SPL should be
included in all new PHP releases (as far as I understand it).
Please quote the exact error message you get, and please
also include some information about the version of PHP you
are using --- there has been some problems with strange bugs
in early versions of the 5.x series...
