Get amount of method parameters

[flaab]

Hi =)

 

Php has some method related functions like method_exists to check wether a function exists in a class. I need a function that returns me how many parameters does a function of a class NEED to be executed, is there any?

 

Thanks.

func_get_args().

Sorry, just re-read your post. Use func_num_args().

Thanks but i'm not pretty sure if this is what i need.

 

What I need is checking how many parameters a function needs to be executed...before executing it =)

 

For example:

 

1. We want to execute function foo of class fooClass and provide an array of parameters

2. We check if the function foo of fooClass can be executed with the amount of parameters passed

3. If the array fits the number of required parameters, we execute it.

4. If not, we do not.

 

It has to be done from outside...

Ah yeah. I thought that might be the case. You will need to use refection.

Thanks!

 

I've been reading it so far and I haven't figured out the way it might help me =(

 

Usually, when we execute a method without all required parameters, we get a warning message displayed in our browser, right?

 

I would like to make that an error  and do not displaying the result.

 

Example:

 

class foo {

 

      public function whatever($a, $b) { }

 

}

 

So if we try to execute foo::whatever(4,5) it works, but if i try to execute foo::whatever(4) it throws an execution error insted of a warning.

 

Maybe catching the exception like this?

 

try {

 

      foo::whatever(4);

 

} catch (Exception $e) {

 

      // Code here

 

}

 

Will that work?

No, it does not xDD
