Filters

Each of the methods that allow you to retrive a single variable contain a $filters parameter, which is a string of words delimited by a period and defines the filters to apply to the variable before returning it. Below explains the available filters:

• trim - Passes the variable through the trim() function, stripping whitespace from both sides.
• escape - Applies the filter_var() function with option FILTER_UNSAFE_RAW
• lower - Lowercases the value
• upper - Uppercases the value
• title - Titlecases the value
• strip_tags - Applies the strip_tags() function against the value
• digit - Deletes all non-digit characters from the value.
