The FormatAbstract class implements the FormatInterface interface with basic functional behavior and adds common helper functions for new formats:

• setContentType
• callContentType
• sanitizeHtml
• array_trim

#Functions

#The array_trim function

The array_trim function receives an array of strings and returns the same array with all elements trimmed (like using the trim function on all elements)
