Prior to the ThinkPHP3.1 version, if you need to set up automatic validation or auto-completion, in general must be defined in the model, or through the SetProperty method to dynamically set the properties to complete, the disadvantage is that it is not easy to dynamically change and adjust.
The ThinkPHP3.1 version adds auto and validate two consecutive operations to the model class to dynamically set

The above is the code for reloading the auto-increment operator. The auto-increment operator is similar. Note: an int type parameter in an auto-increment function with a suffix is only a sign of the compiler and is not used in the function.

++ I: Before using I, perform the auto-increment action;
I ++. After I is used, the auto-increment action is performed.
For example: (1) I = 1, j = I ++; // J = I ++, that is, J references the I value first, and then I completes the ++ action.
Printf ("% d, % d \ n", I, j); // The result is I = 2, j = 1
(2) I = 1, j = ++ I; // J = ++ I, that is, I first complete the ++ action, and then J references
