Flesch-Kincaid Readability: Improve PHP function

Question

I wrote this PHP code to implement the Flesch-Kincaid Readability Score as a function:

function readability($text) {
    $total_sentences = 1; // one full stop =         


        

Answer 1

I actually don't see any problems with that code. Of course, it could be optimized a bit if you really wanted to by replacing all the different functions with a single counting loop. However, I'd strongly argue that it isn't necessary and even outright wrong. Your current code is very readable and easy to understand, and any optimizations would probably make things worse from that perspective. Use it as it is, and don't try to optimize it unless it actually turns out to be a performance bottleneck.
