PHP 클래스 yii\caching\ExpressionDependency

ExpressionDependency will use eval() to evaluate the PHP expression. The dependency is reported as unchanged if and only if the result of the expression is the same as the one evaluated when storing the data to cache. A PHP expression can be any PHP code that has a value. To learn more about what an expression is, please refer to the php manual. For more details and usage information on Cache, see the guide article on caching.
