在PHP上退出内部函数

Question

Can I use this exit on a public api php OR it's an unsafe method? I'm asking that because I want to show the error to api user without back to mainFunction.

class Apiclass{
    private extraPrivateFunction($var){
        if($var == 1){ 
          exit(json_encode(array('status' => 'error','message' => 'error 1 is 1'))); 
        }
    }
    public mainFunction(){
        $number = 1;
        $this->extraPrivateFunction($number); 
    }
}

Thx guys.

Yes, it works, just try this code:

class Apiclass{
    private function extraPrivateFunction($var){
        if($var == 1){ 
          exit(json_encode(array('status' => 'error','message' => 'error 1 is 1'))); 
        }
    }

    public function mainFunction(){
        $number = 1;
        $this->extraPrivateFunction($number); 

        echo "Never Gets Here";
    }
}

$a = new Apiclass();
$a->mainFunction();
