check params required in php

is there a way to find out how many parameters/arguments does the function expect?

lets say

function foo($par,$bar=false){
   ...
}


//fictional function below
echo numbr_of_params('foo'); // should return 1// as $bar is optional :)

You'd have to use the Reflection functions in PHP, such as ReflectionFunction, especially ReflectionFunction::getParameters

    $reflection = new ReflectionFunction($function_name);
    $reflection->getNumberOfParameters();
    $reflection->getNumberOfRequiredParameters();
