Back and forth, unable to collect data to understand what might be behind this, I get the following error:
Recursivedirectoryiterator::__Construct(path/to/directory) [recursivedirectoryiterator. -Construct]: failed to open dir: Too Many open files
The server where this error arises is running Apache/2.2.24 and PHP/5.3.22.
$workingPath = "caminho/para/directoria";
$iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($workingPath),
RecursiveIteratorIterator::SELF_FIRST
);
$files = iterator_to_array($iterator, true); /* tentativa de abafar o erro
como sugerido num tópico do SOEN
mas sem sucesso em resolver a questão */
foreach ($files as $file) {
// código a executar por cada ficheiro localizado
}
Question
How can I correctly assess the cause of this error and/or find out if there are limits I do not know that may be causing the same?
@Bacco I am not indicating anything in that sense... I actually assumed that after each step of the cycle the iterator itself would close the previous file!

@Bacco This example is the same code I use in the question, but I am passing a parameter to the iterator. My conversion from iterator to matrix is a step I just applied to see if it solved the question. Regarding
foreach()vswhile(), I don’t think that’s the problem, but I’ll try...– Zuul
Also try the flag "Filesystemiterator::SKIP_DOTS" in Directoryiterator so it doesn’t enter "recursion recursion":
RecursiveDirectoryIterator($workingPath,FilesystemIterator::SKIP_DOTS)(I don’t know if it helps, I’ve never used these iterators)– Bacco
@Bacco I read this topic, but in the place where the iterator is running, it’s a temporary location that has up to 6 files at most :/ So... I don’t know...

But what about the tree? You’re using Recursivedirectoryiterator, not Directoryiterator, so it’s going in the subfolders.

I left the translation of the answer downstairs, in case it’s useful to someone else. If this is another case, I delete, and/or you can put a correct answer as soon as I find out. If I think of anything else, I’ll let you know. I’ll delete the comments from above, then delete this one.

If you can, test with Directoryiterator instead of Recursivedirectoryiterator just to see if the error changes.
– Bacco
@Bacco The operation is to go to the main folder and its sub-folders, locating a particular file and thumbnails! At most it is 5 directories so it gives a total of 6 files. But I am running tests...
