=== Стандарты ===
  - Use ' instead of " for strings as default string enclosing. This is a performance issue, and prevents a lot of inconsistent coding styles.
  - Don't use uninitialized variables. These errors can be avoided by using the built-in isset() function to check whether a variable has been set.
