How to get error information when there is an error in PHP chain call

The error message here is not a simple string. For example, during the chain call process, a certain function may need to return an array when it does not meet a certain condition, and directly report an error, saying that the array cannot call the next function, but how? Is it possible to stop calling further when a certain function in the middle returns?

Is it like this below?

error) { //do xxx } return $this; } function funcB() { if (! $this->error) { //do xxx //模拟发生错误 $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);
