komtaki/visibility-recommender

Analyze of PHP file, it will suggest the recommended visibility on PSR-12 by modifying the constants directly.

4.3 Properties and Constants Visibility MUST be declared on all properties.

Visibility MUST be declared on all constants if your project PHP minimum version supports constant visibilities (PHP 7.1 or later).

The recommended access modifiers are public, private and protected.

Feature

• Three kinds of public, protected, private can be given to public object constants automatically.
• Only minimal changes are required, and all line breaks and spaces are preserved.
• Supported files
  • Mixed classes with and without namespaces.
  • A mixture of constants with and without access modifiers.
  • Plain view files.
• Not supported
  • Functions that can recover constants by string concatenation, such as eval() and constant().

Roughly pattern

Of course, we don't know if the constant reference is constructed by string concatenation using eval.

public

• Constants are fetched by the unique class name other than self, parent, and static.

protected

• Constants are fetched by self, parent and static from inherit classes.
• Constants are fetched by static from own classes.
• Constants with the same name are declared in parent and children classes in the inherit relationship.

private

• Constants that do not fit into any of the above patterns. Following example.
  • Constants declared in own class and are fetched only in own class by self.
  • Constants are seemed to not used from anywhere.
