Question

My question is pretty much like this one: PHP: Get argument count

Except that I need to count the parameters (arguments if you prefer) of a method, but this method is inside a object.

I tried this:

    $reflection = new ReflectionFunction($_SITE,$acao);
    $qtdArgumentos = $reflection->getNumberOfParameters();

and this :

    $reflection = new ReflectionFunction($_SITE->$acao);
    $qtdArgumentos = $reflection->getNumberOfParameters();

and got this error:

Fatal error: Uncaught exception ‘ReflectionException’ with message ‘Function $_SITE,$acao() does not exist’ in C:\wamp\www\project\index.php:20
Stack trace:
#0 C:\wamp\www\project\index.php(20): ReflectionFunction->__construct(‘$_SITE,$acao’)
#1 {main} thrown in C:\wamp\www\projeto\index.php on line 20

Does anyone knows another way to count the number of arguments of a method is inside a object or a workaround for my code?

Answer 1

I think what you need is ReflectionMethod

 $reflection = new ReflectionMethod($_SITE, $acao);
 $qtdArgumentos = $reflection->getNumberOfParameters();
