Question

I am looking at optimization options, and after checking SO questions, I don’t quite see an answer for what I am trying to do. Hopefully that doesn’t indicate that what I am doing is a bad practice!

I have an intranet application that loads page content via ajax calls to php files. A lot of the php files have a mixture of php, JavaScript, even some HTML, specific to the interface functionality that they load into the main interface. I was wondering about minifying or compressing these files. Is there a way to do it, or am I stuck because I have mixed languages?

Update: Concerning accepted answer:

I have accepted wildpeaks answer because I think it most closely answers my original question. However, this is one of those times when I wish I could accept two answers because I think the answer Igor Zinov’yev provided has given me perhaps a more important design decision to think about. For that reason I have given a +1 to his answer, as I imagine others will too. Hope that makes sense and is within the SO rules.

Answer 1

Your PHP script generates the Javascript code, so it can minify the code before outputting it: generate the code in a variable, then pass that variable to the minifier, and only then output to the browser.

Here’s a PHP library for that.
