Some PHP warnings were generated in the configuration panel and during a restore when using PHP >= 7.2 due to the changed count() behavior in these PHP versions.
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
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
