function camelcase($str){    return    preg_replace_callback('/([-_]+([a-z]{1}))/i',function($matches){        return strtoupper($matches[2]);    },$str);}

To a regular expression version of the

preg_replace('/-([A-Za-z])/e',"strtoupper('$1')",$str)

function camelCase($value){     $studly = ucwords(str_replace(array('-', '_'), ' ', $value));     return str_replace(' ','',lcfirst($studly));}echo camelCase('ask-simple-answer');

"Ask-simple-answer" converted to "Asksimpleanswer"

This should be camel case, just think of Laravel has this function, slightly modified, copied over
