dbx_compare() returns 0 if the row_a[$column_key] is equal to row_b[$column_key], and 1 or -1 if the former is greater or is smaller than the latter one, respectively, or vice versa if the flag is set to DBX_CMP_DESC. dbx_compare() is a helper function for dbx_sort() to ease the make and use of the custom sorting function.
The flags can be set to specify comparison direction:
DBX_CMP_ASC - ascending order
DBX_CMP_DESC - descending order
DBX_CMP_NATIVE - no type conversion
DBX_CMP_TEXT - compare items as strings
DBX_CMP_NUMBER - compare items numerically
See also dbx_sort().
