colima: PHP code has problem reading files from host-mounted volume

PHP code running inside a container in some cases fails to access files from outside the container.

This is a local development setup with a volume mounted to the php container from outside (ie. it is shared between the container and host).

Steps to reproduce

Save the following as test.php:

<?php
$dir = new RecursiveDirectoryIterator(__DIR__);
$iterator = new RecursiveIteratorIterator($dir);
$iterator->setMaxDepth(0);
$files = iterator_to_array($iterator);
echo "Number of files: ".count($files).PHP_EOL;

Running php test.php outside Docker correctly prints out the number of files in the directory: e.g. Number of files: 12 Running it inside a container (ie. with docker exec) prints out Number of files: 0

Here is a one-liner to test it with (after creating test.php)

docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.4-cli php test.php

(Should never print Number of files: 0 because the directory contains at least the test.php file itself)
