I want to append md5 hash to css and js files to able to long-term cache them in browser.
In Python Django there is a very easy way to do this, static template tag https://docs.djangoproject.com/en/1.10/ref/templates/builtins/#std:templatetag-static
I'd like a library that does exactly the same thing in PHP, including generating the hashes at build time, not runtime.
I've seen an old same question on SO:
hash css and js files to break cache. Is it slow? , but it never got an answer about how to do the md5 hash, so I'm asking again.
