Find All References

The Find All References window lists all the occurrences of a symbol. In case the reference is not sure, e.g. it is a part of a dynamic call or it is a part of a callback specified as a string, the occurrence is grayed.

The feature also looks into string values to match for function names or string parameters of define() or constant() to match for global constant names. Types and parameters within PHPDoc comments are also matched.

Note: To improve finding class member references, use type hints or PHPDoc type hints. This helps the editor to resolve types more precisely.
