This works but is uglier than hell, basically it’s iterating through two separate portions of a sub array, seeing if there’s a greatest common denominator besides 1 in the values of both sub arrays, and if there is, multiplying the base value by 1.5
Sorry for the sloppy code ahead of time.

What it does
What this class does so far is split the csv one array, split content prior to ; and after into two sub arrays. Count the consonants and vowels of both, find if there is a greatest common denominator between the two subsections for each C V or mixed letter pair, and create a value to assign a band to a product.
What really needs to do though
The highest value generated should be associated with the band that created that high value. So what I am trying to really do is associate a name to a band depending on how high of a score it ultimately generates. I’m about half way through =(
As you guys can see, this code is a mess, literally. All I really want is to assign a name to a band based on the numbers I’m generating.
I have to agree with everyone else here… but I’d like to add:
Instead searching for how to traverse
$this->digitsmore simply, you should strongly consider rethinking the structure of the data in$this->digits.Furthermore, lumping everything into a single array doesn’t always make sense. But when it does, the structure can be thought out so that it is intuitive and can be traversed easily.
Without more information about what this is doing, there is no way for us to suggest how to restructure your data / class. A start would be giving us what a sample
$this->digitsarray looks like. Also, some more information about your problem would be good (like how this method is used).
