Unable to use getimagesize on HEIC/HEIF images

[earthiverse]

Description

I downloaded the heic from the pull request #18940, and that one does work, but none of the sample images I downloaded from https://heic.digital/samples/ work.

The following code:

<?php

$dir = __DIR__;

$allowedExt = ['jpg', 'jpeg', 'heic', 'heif'];

foreach (new DirectoryIterator($dir) as $file) {
    if ($file->isDot() || !$file->isFile()) {
        continue;
    }
    
    $ext = strtolower($file->getExtension());
    if (!in_array($ext, $allowedExt, true)) {
        continue;
    }
    
    $path = $file->getPathname();
    $info = getimagesize($path);
    
    if ($info === false) {
        echo "Failed: $path\n";
        continue;
    }
    
    [$width, $height] = $info;
    echo "$path => {$width}x$height\n";
}

Resulted in this output:

seems those photo were taken with samsung camera, is different with the photo from iphone.

It also applies to pictures made by Apple devices like an iPhone. I tried to test this with an image transferred from my phone and get the same results. The pictures in the image test folders though do seem to work.

The website says (can't verify, but have no reason not to believe them) that 2 are from the iPad Air Gen 5, and 2 are from the iPhone 12 Pro.

I also tried the images from https://github.com/tigranbs/test-heic-images/tree/master after googling and finding AcademySoftwareFoundation/OpenImageIO#2794

image4.heic from there does work with getimagesize, but the other 3 do not.

tigranbs/test-heic-images#1 implies that image4.heic might be the only one with metadata

@iluuu1994
I had checked the code, in fact, the error happen in ext/standard/libavifinfo/avifinfo.c.
Some heic image didn't have field 'iprp' in meta box, so libavifinfo can not find field "ispe" which is used to parse image width and height.
Suggest to involve owner of libavifinfo to fix.

I don't work on this area of PHP, I'll leave this up to somebody else. Maybe @devnexen?
