Php json_encode implementation and Chinese garbled code solution

$ Arr = array ('a' => 1, 'B' => 2, 'C' => 3, 'D' => 4, 'E' => 5 );

Echo json_encode ($ arr );

// Result

// {"A": 1, "B": 2, "c": 3, "d": 4, "e": 5}

/*

The following describes a json_encode Chinese garbled problem.
The solution is to use the urlencode () function to process the following. Before json_encode, urlencode () is used to process all the content in the array, and json_encode () is used to convert the content into a json string, finally, use urldecode () to convert the encoded Chinese characters back.
