  5.  
  6. Variables:

  8. $txt_limiter = max amount of letters in the string that should be seen
  9. $txt_sep = the separator used to end the string (like string...)
  10. $tipo
  11. 	1 - from start to end without relating words (when it reaches the $txt_limiter it breaks the string)
  12. 	2 - from start to end relating words (when it reaches the $txt_limiter it finds the next space to break the string)
  13. 	3 - from end to start without relating words (when it reaches the $txt_limiter it breaks the string)
  14. 	4 - from edn to start relating words (when it reaches the $txt_limiter it finds the next space to break the string)
