What is the purpose of php's cache technology, especially the smarty technology? I know it is cache, but what is the main purpose? ------ solution ------------------ for example, a page, A lot of operations are required to display the results. if each access operation is required, it will be slow. Therefore, when the first execution is performed, the results are saved and the results are displayed directly during the next access. This reduces the number of operations and responds quickly. Of course, you need to set an expiration time for the purpose of php's cache technology.
In particular, smarty technology knows cache, but what is the main purpose?
------ Solution --------------------
For example, a page requires a lot of operations to display the results. if each access requires an operation, it will be very slow.
Therefore, when the first execution is performed, the results are saved and the results are displayed directly during the next access. This reduces the number of operations and responds quickly.
Of course, you need to set an expiration time. if it expires, it will be generated again.
