PHP-FPM FilesMatch and ProxyPassMatch Interchangeability?

Question

Are FilesMatch and ProxyPassMatch interchangeable when proxying php-fpm, and if so are there any circumstances where one would be used over the other?

Currently I am using ProxyPassMatch via a vhost block as per the many online tutorials.

<FilesMatch \.php$>
    SetHandler "proxy:unix:/var/run/php-fpm/php-fpm.sock|fcgi://127.0.0.1:9000/"
</FilesMatch>
<Proxy "fcgi://127.0.0.1:9000/" enablereuse=on max=10>

vs

ProxyPassMatch ^/(.*\.php(/.*)?)$ unix:/var/run/php-fpm/php-fpm.sock|fcgi://127.0.0.1:9000/

Answer 1

One important difference is ProxyPassMatch ignores deny access of .php files in .htaccess.

FilesMatch is better.
