Apache shows PHP code if .php in URL is not lowercase

[nizar787]

If you enter a URL in browser pointing to a PHP file and .php at the end is not all lowercase (e.g. .phP, .pHp, .PHP, like example.com/index.PHP), Apache shows content of the PHP file.
This is because of this config in /etc/apache2/conf-enabled/docker-php.conf:

<FilesMatch .php$>
SetHandler application/x-httpd-php

To fix it, FilesMatch's regexp should be case-insensitive:

<FilesMatch .(?i:php)$>
SetHandler application/x-httpd-php

I can make a pull request but should the change be made in this file?

php/apache-Dockerfile-block-1

echo '<FilesMatch .php$>'; \
