PHP call_user_func vs. just calling function

Question

I\'m sure there\'s a very easy explanation for this. What is the difference between this:

function barber($type){
    echo \"You wanted a $type haircut, no         


        

Answer 1

With PHP 7 you can use the nicer variable-function syntax everywhere. It works with static/instance functions, and it can take an array of parameters. More info at https://trowski.com/2015/06/20/php-callable-paradox

$ret = $callable(...$params);
