PHP函数中的return语句[重复]

• Return always return false 3 answers

I'm having some problems with a Return statement in PHP. The thing is that, no matter what happend inside my function I always get a false value out of the function. I really think that is because of the Return statement because I try to use it in other functions and I don't get a diferent value.

public function valid_token ()
{
    if (!isset($_SESSION['token']) || $this->token != $_SESSION['token'])
    {
        $this->errors[] = "Formulario incorrecto";
    }

return count($this->errors)? 0 : 1;
}

Out of this function I always get a false value (0). The same happends when i call:

public function valid_data () 
{
    if (empty($this->sectorName) || empty($this->sectorInfo) || empty($this->sectorCat))
    {
        $this->errors [] = "Datos incorrectos";
    }

return count($this->errors)? 0 : 1;
}

Of course, I call both functions when I have already sent the form and have set the token.

Because you are just counting not checking,Try this

return count($this->errors) > 0 ? 0 : 1;
