    ------------------------------------------------------------------------

    SUMMARY

    PHP intended to handle the administration of MySQL over the Web. Currently
    it can create and drop databases, create/drop/alter tables,
    delete/edit/add fields, execute any SQL statement, manage keys on fields,
    manage privileges, export data into various formats and is available in 47
    languages".
