ParamsReturnSource
Write value(s) to the cache.
This adapter method supports multi-key write. By specifying `$key` as an associative array of key/value pairs, `$data` is ignored and all keys that are cached will receive an expiration time of `$expiry`.

Parameters

  • string|array $key The key to uniquely identify the cached item.
  • mixed $value The value to be cached.
  • mixed $expiry A Unix timestamp or `strtotime()`-compatible string indicating when `$value` should expire. If no expiry time is set, then the default cache expiration time set with the cache configuration will be used.

Returns

closure Function returning boolean `true` on successful write, `false` otherwise.
