function VariableAnalysisSniff::markVariableAssignment

* Record that a variable has been defined and assigned a value. * * If a variable has been defined within a scope, it will not be marked as * undefined when that variable is later used. If it is not used, it will be * marked as unused when that scope ends. * * Sometimes it's possible to assign something to a variable without * definining it (eg: assignment to a reference); in that case, use * `markVariableAssignmentWithoutInitialization()`. * *

Parameters

string $varName: * @param int $stackPtr * @param int $currScope * * @return void
