Description:
------------
DirectoryIterator (and RecursiveDirectoryIterator) returns fewer files than should be in some cases.
But scandir/opendir+readdir returns all files.
It produces only in alpine linux in my tests. centos/windows doesn't have the problem.

Test script:

Maybe it is irrelevant but if you set the index directly is it always an element?

$arr = array(0 => null);
$i = 0;
//example foreach
while($i < 5) {
if(is_null($arr[0]))
$arr[0] = 'value';
$arr = $arr + array($i => 'value');
++$i;
}
var_dump($arr);
