function in CakePHP Model returning int instead of null

Question

I have a model called Api.

Which I'm accessing from a shell Script.

My shell script function that is running:

public function verifyTransactions(){
        $result =$this->out($this->Api->verifyNumber());
        $this->out(var_dump($result));
    }

this outputs]

int(2)

Here is the function in the Api model:

    public function verifyNumber(){
    return null;
}

I've tried making return null into return false (boolean) , return a string like "jibberish"

But still when I print it out I get the type as int with a different number in, like an object reference or something.

I'm sure I've over looked something real simple, if somebody could point it out that would be awesome ;)

Thanks

Edit:

Ah the error is I've got $this->out in there twice

If you are not going to output the returned (null) value and just want to use it for comparisions, why not avoid using $this->out alltogether?

Leave your Api method exactly the same and the verifyTransaction method could simply be ...

public function verifyTransactions(){
    var_dump($this->Api->verifyNumber());
}

Or ..

public function verifyTransactions(){
    if(is_null($this->Api->verifyNumber()){
        //do null stuff. Could even use the out method you have been trying to avoid...
        $this->out('got null back from Api');
    }
}

Currently you are setting a variable with the $this->out helper... $this->out is meant for handling readable output, never for setting variables... Don't do ...

 $result =$this->out($this->Api->verifyNumber());

Just ...

 $result = $this->Api->verifyNumber();

Shell::out() returns the number of bytes written or false on error, so I'm not sure why you would expect it to return something else.

See http://api.cakephp.org/2.4/class-Shell.html#_out

If you need to reuse the return value of Api::verifyNumber(), then you should directly store it in a variable first.

public function verifyTransactions(){
    $result = $this->Api->verifyNumber();
    $this->out($result);
    // ...
}
