/**
* Sanitizes given array or value for safe input. Use the options to specify

* value). Valid filters:
*
* - odd_spaces - removes any non space whitespace characters
* - encode - Encode any html entities. Encode must be true for the `remove_html` to work.
* - dollar - Escape `$` with `\$`
* - carriage - Remove `\r`
* - unicode -
* - escape - Should the string be SQL escaped.
* - backslash -
* - remove_html - Strip HTML with strip_tags. `encode` must be true for this option to work.
*
* @param string|array $data Data to sanitize
* @param string|array $options If string, DB connection being used, otherwise set of options
