/*
  What do these lines of code do exactly?

  The ini_set function will try to override the configuration found
  in your PHP ini file.

  The display_errors and display_startup_errors are just two of the
  directives that are available. The display_errors directive will
  determine if the errors will be displayed or hidden to the user.
  Usually, the dispay_errors directive should be turned off after
  development.

  The display_startup_errors, however, is a separate directive
  because the display_errors doesn’t handle the errors that will be
  encountered during PHP’s startup sequence. The list of the
  directives that can be overridden by the ini_set function is found
  in the official documentation.
