当foreach循环进入变量时，PHP函数错误处理和返回

Question

*problem/confusion on how to handle this type problem in the php object oriented coding *

I have customer class which i need to suspend services for customers, however when the customer has pending work types for a service, i need to return a false for the calling function to do the error handle (i cant do it here becos it could be a email,output, or html)

however i am confused how to handle this as if use following code it will return false only on the last condition on the foreach loop i guess, any idea on how to handle this in the coding point of view

 /**
   * return false on failier 
   * Customer suspend all services for this customer
   * 
   */
  public function suspendServices(){

    $pending=false; 

    foreach ($this->services() as $service) {

    $pending = $service->hasPendingWorktypes();

    if($pending === true) {
        return false;
    }   
    $service->state()->changeTo(8);  

    }//end of foreach services 

  }//end of function

Exceptions is perfect for this job. The business method calling for the services can then onwards handle the part efficiently for the correct outcome.

public function suspendServices(){

    $pending=false; 

    foreach ($this->services() as $service) {

    $pending = $service->hasPendingWorktypes();

    if($pending === true) {
        throw new PendingExcpetion(); //Throw the exception
    }   
    $service->state()->changeTo(8);  

    }//end of foreach services 
}
