How to update CPHPCache cache data in 1C-Bitrix?

Question

PHP

Hello! There is a cache with a lifetime of 1 hour (3600), I store an array, but sometimes I need to update the data inside the cache, how to do this?

Answer 1

Indeed, this issue is not considered in the official documentation.
If there is a valid cache with an unexpired TTL in the cache, then you will not be able to update it.
The correct solution is to clear the cache and add a new value,
but you don't need to call ->clearDir(), just call ->clear() with the appropriate tag

Answer 3

For example, tag and clear by tag. Or, if this is a component cache, then clear by the tag that the component puts.
