  12    This driver only supports the original MySQL driver in transactional mode. It
  13    is deprecated in PHP version 5.5 and removed in PHP version 7. It is deprecated
  14    as of ADOdb version 5.20.0. Use the mysqli driver instead, which supports both
  15    transactional and non-transactional updates
  16  
  17    Requires mysql client. Works on Windows and Unix.
