Course Introduction:Return value rules for custom PHP functions: All functions must return a value (can be NULL). Use the return keyword or implicitly return the last expression value. The return value must be the value itself, not a reference.

Course Introduction:Custom functions in PHP can return values of specified types through the return statement, including strings, numbers, arrays, and objects. Practical case: -Return string: functiongreet($name){return "Hello,$name!";} -Return array: functionget_user_data($id){return["name"=>"John","email"=> "john@example.com"];}

Course Introduction:In PHP extension development, it is crucial to define the input parameters and return value types of custom functions. Specific steps include: defining type qualifiers: void has no return value, int is used for basic types, arrayobject is used for object types, and mixed is used for any type. . Define the input parameter type: use the zend_arg_info structure to specify the parameter name, type, and whether to pass by reference. Define the return value type: use zend_return_reference* pointer, specify the type and whether null is allowed. Register a custom function: use zend_register_functions and pass in parameter and return value type information.

Course Introduction:In the Go language, you can define function return values by creating custom types to enhance flexibility and allow data to be returned in a specific format or structure. Defined by syntax: funcfunctionName()(returnType1, returnType2,..., returnTypeN){}, for example, the function GetPerson() can return a custom structure Person containing name and age attributes.

Course Introduction:Function return value is crucial in C++, which allows the function to return data of a specified type: the return value type defines the type of data returned by the function, including basic types (such as int, float) and custom types (such as pointers, references). The return value meaning varies based on the function's intent, such as returning a result, indicating status, providing a reference, or creating a new object.
