商业规则定义或限制商业的某些方面。在给定的指定上下文（数据）中，商业规则始终解析为真或假。

形式化规范：// Given {context} When {condition(s)} Then {pass} Or {fail}

用法

直接使用

$rule = (new BusinessRule())->context([])->condition(function($context){ return true; });

if ($rule->fails()) {
    // Execute fail logic
}

if ($rule->passes()) {
    // Execute pass logic
}

扩展到单独的类。允许重用（避免业务逻辑重复）

// 1. Specify the business rule class
class AllowAccessRule extends BusinessRule {
    function __construct() {
        $this->condition(function($context){
            return ($context['user']->isEmailConfirmed() AND $context['user']->isActive());
        });
    }
}

// Use the shortcut init function with the context to initialize the rule
if (AllowAccessRule::init(['user'=>$user)->fails()) {
    die('You are not allowed access to this part of the website');
}
