D6670: Allow non-scalar constants in PHP language support

[Matthijs Tijink]

mtijink created this revision.
mtijink added a project: KDevelop.
Restricted Application added a subscriber: kdevelop-devel.

REVISION SUMMARY
  Newer PHP versions allow almost any expression in the definition of a constant, as long as it is actually constant. This is hard to test in the parser (and impossibly in the grammar definition) though, so this diff just allows any expression.

TEST PLAN
  I edited some tests to make sure the new behaviour is allowed.

REPOSITORY
  R52 KDevelop: PHP Support
