camelCase to dash - two capitals next to each other

Question

I\'m using this function to convert CamelCase to dashed string:

function camel2dashed($className) {
    return strtolower(preg_replace(\'/([^A-Z-])([A-Z])/\'         


        

Answer 1

Use a lookahead assertion:

function camel2dashed($className) {
    return strtolower(preg_replace('/([a-zA-Z])(?=[A-Z])/', '$1-', $className));
}
