Perhaps modify the following line in robot_functions.php to insert words or telephone numbers:
Code:
// v.1.8.7
if (strlen($key) > SMALL_WORDS_SIZE and strlen($key) <= MAX_WORDS_SIZE and !isset($common_words[$key]) and ereg('^['.$phpdig_words_chars[PHPDIG_ENCODING].'#$]',$key))
// v.1.8.8 RC1
if (mb_strlen($key) > SMALL_WORDS_SIZE and mb_strlen($key) <= MAX_WORDS_SIZE and !isset($common_words[$key]))
Note though that PhpDig uses a space to separate 'words' so telephone numbers like "(xxx) xxx-xxx" for example might need to be considered near the $separators = " "; line in the robot_functions.php file.
