The reason is that the subclass defines the same method name as the parent class.

Subclass:
Private function return_json ($ message, $ result = 'true '){
$ Data = array ();
$ Data ['result'] = $ result;
$ Data ['message'] = $ message;
Self: echo_json ($ data );
}

Private function echo_json ($ data ){
If (strtoupper (CHARSET) = 'gbk '){
$ Data = Language: getUTF8 ($ data); // when the website GBK uses encoding, it is converted to a UTF-8 to prevent problems with json output Chinese Characters
}
Echo json_encode ($ data );
}

Parent class:

/**
* Return the json status.
*/
Protected function return_json ($ message, $ result = 'true '){
$ Data = array ();
$ Data ['result'] = $ result;
$ Data ['message'] = $ message;
Self: echo_json ($ data );
}

Protected function echo_json ($ data ){
If (strtoupper (CHARSET) = 'gbk '){
$ Data = Language: getUTF8 ($ data); // when the website GBK uses encoding, it is converted to a UTF-8 to prevent problems with json output Chinese Characters
}
Echo json_encode ($ data); die;
}

Solution

Change private in the subclass to protected, or avoid duplicate methods. In this example, we have already defined the same method, and deleted the two methods by subclass.
