phan/phan 2.6.1

Release 2.6.1 supporting PHP 7.0-7.4 syntax

on PHP Packagist

New features(CLI, Configs):

• Add a --dump-ctags=basic flag to dump a tags file in the project root directory. (https://linux.die.net/man/1/ctags)
  This is different from tool/make_ctags_for_phan_project - --dump-ctags=basic has no external dependencies.

New features(Analysis):

• Infer that the real type set of the key in foreach ($arrayVar as $key => ...) is definitely an int|string
  in places where Phan previously inferred the empty union type, improving redundant condition detection. (#3789)

Bug fixes:

• Fix a crash in phan --dead-code-detection when a trait defines a real method and phpdoc @method of the same name (#3796)

Miscellaneous:

• Also allow netresearch/jsonmapper@^2.0 as a dependency when enforcing the minimum allowed version (#3801)
