More of a style thing, but for booleans I try to give them a verb name like:

isActive
isDefined
hasName
hasColor

which I’ve found makes my code read more semantically when the variables are used in conditional statements and loops

<?php

//Naming convention
$first_name = 'Mike'. // all lower case with underscore separators
function updateProduct() // camelCase
class ProductItem // StudlyCaps
const ACCESS_KEY = '123abc'; // all upper case with underscore separators

//output
echo 'Hello World';

//variable declaration
$name = 'Mike'; //string
$isActive = true; //boolean
$number = 25; //integer
$amount = 99.95; //float
...

You seem to introduce a naming convention of camel case for var names, then immediately contradict it with $isActive?

Pretty good work, I am not sure, if it's only me, I must have used "while and do-while loop" no more than 2-3 times in the last 4 years

Nice list. Note: In at least 2 cases you use __construc where it should be __construct

Eric The Coder • Dec 20 '20

Good catch. Corrected.

I need to benchmark it again, but ++$i is a micro optimizion you can use on your for loops. IIRC, do..while is another micro optimization you replace your while loops with, if you can guarantee at least one iteration.
