Returning Values by Reference

Summary

In this chapter you looked at how to return values from internal functions both directly by value, as a reference, and through their parameter stack using references. You also got a first look at argument type hinting using Zend Engine 2's zend_arg_info struct.

In the next chapter you'll delve more deeply into accepting parameters both as elementary zvals and using zend_parse_parameters()'s powerful type juggling features.
