Nice! That fixed the $file holding the value between iterations
Test 1: ($file now is reset on iteration)
<?php
foreach (new DirectoryIterator('.') as $file) {
echo "\n--\n";
var_dump($file);
preg_match("/xxx/", $file);
var_dump($file);
echo "--";
}
--
object(DirectoryIterator)#1 (0) {
}
string(1) "."
--
--
object(DirectoryIterator)#1 (0) {
}
string(2) ".."
--
What are the possibilities of thrown E_STRICT or E_WARNING, since
the object gets lost? Or should this simply be a documented
behaviour? If possible, any pointers where to consider applying them
at?
>From what I've seen there are a lot of convert_to_xxx_ex()'s around
and can cause a some of unexpected results, without some sort of
notice. Of course ideally, an attempt to fetch a __toString()
value would be really nice :) I'm way over my head at this point.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!
