I want to write a PHP application that is going to do some checks

  • 0

I want to write a PHP application that is going to do some checks first, to ensure an optimal and secure environment. I’m sure I alone can not think of everything, so what am I missing?

  • Ensure MySQL username/password can SELECT, INSERT etc
  • Update PHP timezone
  • Check for register_globals and warn if enabled
  • Ensure /install is deleted
  • If no config file make one
  • Ensure config file doesn’t have write permissions
  • Erase cache folder contents if over 50mb or so
  • Make sure GD and PDO are installed and working

Please answer with any more ideas or if any of the above aern’t a good idea. I probably realise the cache folder thing should be a cron job that runs every week or so.

  1. Have you checked PHPSecInfo? It is going to do some really important PHP security-related configuration tests you should be aware of.
