Sometimes I need to develop a small project like online contest or registration form or survey. Sometime if you using framework like Laravel is simply too time consuming and made by yourself is the quickest choice. For this situations I have found medoo.in as database connect system, very useful and secure.

They declare it is:

  • Lightweight

  • Powerful
    Support various common and complex SQL queries.
  • Compatible

and, in the end, it is true for me.
