function VariableAnalysisSniff::markVariableAssignmentWithoutInitialization

* Record that a variable has been assigned a value. * * Does not record that a variable has been defined, which is the usual state * of affairs. For that, use `markVariableAssignment()`. * * This is useful for assignments to references. * *

Parameters

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