protected static function TypogrifyFilter::settingsSerialize in Typogrify 8

Serialize array values.

There must be a better way to do this, but it looks as though trying to save an array-valued plugin setting fails. Our solution is to serialize the settings before saving and unserialize them before using.

Serialize $settings[$key] for each $key in $arraySettingsKeys.

Parameters

array &$settings: The array of plugin settings.
