try catch

Is it like this below?

<?php

class Demo
{
    protected $result;
    protected $error = false;
    
    function funcA() 
    {
        if (! $this->error) {
            //do xxx
        }
        
        return $this;
    }
    
    function funcB() 
    {
        if (! $this->error) {
            //do xxx
            //模擬發(fā)生錯(cuò)誤
            $this->error = true;
            $this->result = ['Ops!', 'Something bad Happened!'];
        }
        
        return $this;
    }
    
    function funcC() 
    {
        if (! $this->error) {
            //do xxx
        }
        
        return $this;
    }
    
    function GetResult() {
        return [$this->result, $this->error];
    }
}

$demo = new Demo();

list($result, $hasError) = $demo->funcA()->funcB()->funcC()->GetResult();

var_dump($result, $hasError);
