ParamsReturnSource
Attempts to apply a set of formatting rules from `$_rules` to a `$params` array.
Each formatting rule is applied if the key of the rule in `$_rules` is present and not empty in `$params`. Also performs sanity checking against `$params` to ensure that no value matching a rule is present unless the rule check passes.

Parameters

  • array $params An array of route parameters to which rules will be applied.

Returns

array Returns the `$params` array with formatting rules applied to array values.
