the emulation of mysql_select_db with the USE statement did not quote the table name so table names which need quotation (which contain dashes for example) were not handled correctly
the emualtion is not needed, see https://github.com/philip/MySQLConverterTool/issues/20
in contrast to mysql_connect, it is not allowed to attach the port or the socket to the host name for the mysqli_connect command. There are separate parameters for that now. This leads to "Access denied for user 'user123'@'localhost' (using password: NO) " errors in the current version if port or socket is specified
This commit converts all mysql_* function to the appropriate counterparts
in mysqli.
I used this tool for most of it:

This makes it possible to continue using MysqlDumper with PHP 7.0
