function to $ a without affecting $ B. In this way, the call is no different from the normal call.
Php rules: $ a = test () is returned as a function reference. The memory address of the $ B variable and the memory address of the $ a variable point to the same place. That is, equivalent to $ a = $ B;
4. cancel the reference
The code is as follows:$ A = 1;
$ B = $;
Unset ($ );
Echo $ B;
Resolution: unset is a reference. it only removes the binding between the variable name and the content of

Parse: unset a reference, just cancels the binding between the variable name and the contents of the variable, does not mean that the content is destroyed, its value is still real.

-oriented architecture, the underlying entities are often not directly published, so that the client can directly perform CRU operations. Instead, some coarse-grained RPC-based service operations are published. To use the Web API framework, we need to modify the default configuration. For example, you must explicitly specify the action name when calling the client:
