Add bookkeeping to lexical-analysis and affect syntax coloring signaling variables which are undefined

cjohansson commented 3 years ago

Stuff left TODO:

Partial re-parse of bookkeeping
IF assignments if ($requests = ...)
Foreach assignments foreach ($item in $items...
For assignments for ($i = 0; $i < ...
Class variable assignments private static $name =
This assignments $this->bla = ...
Self assignments self::$bla = ...
Parent assignments parent::$bla = ...
Global variables should always be signaled as defined ($_GET, $_POST, $_SESSION, $_REQUEST, $_GLOBALS, $_COOKIE)

Class property signaling $this->bla = ..., self::$bla... and parent::$bla...
Catch expressions (\Exception $e)
Anonymous functions $greet = function($name)

Found some edge cases, should not signal about:

class methods $this->random()...
variable assignment(s) in array [$random, $bandom] = $this->myValues()... or array($random, $bandom] = $this->myValues()...
reference variable declaration in foreach foreach ($items as &$item)...
