In PHP, what is the term for the blueprint from which individual objects are created?

In PHP, the term for the blueprint from which individual objects are created is "Class." A class defines the structure, properties, and methods that an object will have. Objects are instances of a class, and they are created based on the blueprint provided by the class. The other mentioned options (Object, Instance, Prototype) are related to objects but do not specifically refer to the blueprint itself. For further details, refer to the PHP documentation on classes and objects: http://php.net/manual/en/language.oop5.php
