Is there a better way of writing v = (v == 0 ? 1 : 0);

isset() vs strlen() - a fast/clear string length calculation

if(isset($string[255])) {

}

"AND" vs "&&" as operator

Actually, I am facing a codebase where developpers decided to use ' AND ' and ' OR ' instead of ' && ' and ' || '. I know that there is difference in operators precedence ( && goes before ' and '), but with given framework (prestashop to be precise) is clearly not a reason. So, my question: which version are you using? Is ' and ' more readable than ' && '? || there is ~ difference?
