Docker - Files Contain Bad Line Terminators - linux

Question

I setup a development environment using Docker on Windows 10. My Dockerfile and docker-compose.yml file uses php:8.2.2-apache, mysql:8.0.32, composer:2.5.3, and phpMyAdmin:5.2.1.
I will admit that getting Docker up and running to basically mimic my old xampp development environment has been incredibly frustrating.
Recently, I added robmorgan/phinx 0.13 to my composer.json. Initially, I ran from the docker container's terminal vendor/bin/phinx init and it successfully created a phinx.php file. I stopped the container, modified my phinx.php file to use values from my .env file. When I reran Docker, back into the container's terminal to run vendor/bin/phinx create <name>, I now get this error in the terminal:
usr/bin/env: 'php\r': No such file or directory
I have read in several places that this is because files have the Windows line terminators instead of the Unix line terminators.
The issue is that I do not understand which file is affected. How can I audit my files to find out what is the culprit?
In case you are curious, this is my docker-compose.yml and phinx.json:
version: '3.9'
services:
webserver:
build: ./docker
image: -redacted-
ports:
- "80:80"
- "443:443"
volumes:
- ./www:/var/www/html
links:
- db
db:
image: mysql:8.0.32
ports:
- "3306:3306"
volumes:
- ./database:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
- MYSQL_DATABASE=${MYSQL_DATABASE}
- MYSQL_USER=${MYSQL_USER}
- MYSQL_PASSWORD=${MYSQL_PASSWORD}
composer:
image: composer:2.5.3
command: ["composer", "install"]
volumes:
- ./www:/app
phpmyadmin:
depends_on:
- db
image: phpmyadmin:5.2.1
restart: always
ports:
- 8080:80
environment:
PMA_HOST: db
<?php
$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();
$databaseName = $_ENV['MYSQL_DATABASE'];
$username = $_ENV['MYSQL_USER'];
$password = $_ENV['MYSQL_PASSWORD'];
return
[
'paths' => [
'migrations' => '%%PHINX_CONFIG_DIR%%/db/migrations',
'seeds' => '%%PHINX_CONFIG_DIR%%/db/seeds'
],
'environments' => [
'default_migration_table' => 'phinxlog',
'default_environment' => 'development',
'production' => [
'adapter' => 'mysql',
'host' => 'localhost',
'name' => $databaseName,
'user' => $username,
'pass' => $password,
'port' => '3306',
'charset' => 'utf8',
]
],
'version_order' => 'creation'
];
And I am running this to load Docker: docker-compose --env-file=./www/.env up

This should find files w/ CRLFs:
find -type f -print0 | xargs -0 file | grep CRLF
