Finding images

[matjazp]

Any better way to find all images? The fastest way. Without script timeout. A lot of images...

$timer = Debug::timer();

$allImages = array();           

foreach (wire('fields')->find('type=FieldtypeImage') as $f) {
    foreach (wire('pages')->findMany("$f>0, include=all") as $p) {
        $images = $p->getUnformatted($f->name);
        foreach ($images as $i) {
            $allImages[] = $i;
            foreach ($i->getVariations() as $variation) $allImages[] = $variation;
         }
    }
}

$totalItems = count($allImages);
echo "All images: " . $totalItems . " Timer: " . Debug::timer($timer);

Only thing I can think of is to limit the search also by template:

foreach (wire('fields')->find("type=FieldtypeImage") as $f) {
    foreach (wire('templates') as $t) {
        foreach (wire('pages')->findMany("template=$t, $f>0, include=all") as $p) {
            // etc...
        }
    }
}

Thx, diogo. Found out that find/findmany is very fast, it's getVariations() call where 95% of time is lost, probably due to filesystem calls (DirectoryIterator). I guess there is no way to improve that?

You could also get the images directly from the assets/files directory with PHP.

I could, but that would give me all the files, not just images. And even I get the images by extension, I would have to know if image is of FiletypeFile of FieldtypeImage, and also would have to differentiate between originals and variations. If PW would store variations in DB... 

Also, I'm searching the forum and cant't find the post, where someone described (could be you?) how to iterate through a lot of pages (all of them) but without running out of memory and execution time.
