• escape_implicit_backslashes

  Escape implicit backslashes in strings and heredocs to ease the understanding of which are special chars interpreted by PHP and which not.

  In PHP double-quoted strings and heredocs some chars like n, $ or u have special meanings if preceded by a backslash (and some are special only if followed by other special chars), while a backslash preceding other chars are interpreted like a plain backslash. The precise list of those special chars is hard to remember and to identify quickly: this fixer escapes backslashes that do not start a special interpretation with the char after them. It is possible to fix also single-quoted strings: in this case there is no special chars apart from single-quote and backslash itself, so the fixer simply ensure that all backslashes are escaped. Both single and double backslashes are allowed in single-quoted strings, so the purpose in this context is mainly to have a uniformed way to have them written all over the codebase.

  Configuration options:

  • single_quoted
    Whether to fix single-quoted strings.
    Allowed types: bool
    Default value: false
  • double_quoted

• explicit_string_variable

  Converts implicit variables into explicit ones in double-quoted strings or heredoc syntax.

  The reasoning behind this rule is the following: - When there are two valid ways of doing the same thing, using both is confusing, there should be a coding standard to follow - PHP manual marks "$var" syntax as implicit and "${var}" syntax as explicit: explicit code should always be preferred - Explicit syntax allows word concatenation inside strings, e.g. "${var}IsAVar", implicit doesn't

  - Explicit syntax is easier to detect for IDE/editors and therefore has colors/highlight with higher contrast, which is easier to read Backtick operator is skipped because it is harder to handle; you can use backtick_to_shell_exec fixer to normalize backticks to strings

• final_class

  All classes must be final, except abstract ones and Doctrine entities.

  No exception and no configuration are intentional. Beside Doctrine entities and of course abstract classes, there is no single reason not to declare all classes final. If you want to subclass a class, mark the parent class as abstract and create two child classes, one empty if necessary: you'll gain much more fine grained type-hinting. If you need to mock a standalone class, create an interface, or maybe it's a value-object that shouldn't be mocked at all. If you need to extend a standalone class, create an interface and use the Composite pattern. If you aren't ready yet for serious OOP, go with FinalInternalClassFixer, it's fine.
