function ConstExprEvaluator::evaluateDirectly

Directly evaluates a constant expression into a PHP value.

May generate Error exceptions, warnings or notices. Use evaluateSilently() to convert these into a ConstExprEvaluationException.

If some part of the expression cannot be evaluated, the fallback evaluator passed to the constructor will be invoked. By default, if no fallback is provided, an exception of type ConstExprEvaluationException is thrown.

See class doc comment for caveats and limitations.
