Php code for converting json format data _ PHP Tutorial

Php code for converting json format data. This article mainly introduces the json format data conversion program in php. We use the json_decode () and json_encode () functions to perform operations conveniently, this article describes how to operate the json format data conversion program in php. We use the json_decode () and json_encode () functions to perform operations conveniently, if you need to learn, refer to this example.

Step 1: Use the json_encode () function to convert data to json data.

The code is as follows:

// JSON format data is represented by arrays in php. $ Arr = array ( 'Firstname' => iconv ('gb2312', 'utf-8', 'sincerity '), 'Lastname' => iconv ('gb2312', 'utf-8', 'Do Not Disturb '), 'Contact '=> array ( 'Email '=> 'fcwr @ bKjia. c0m ', 'Website' => 'http: // www. bKjia. c0m ', ) ); // Encode the array into JSON data format $ Json_string = json_encode ($ arr ); // JSON format data can be directly output Echo $ json_string; ?>

This conversion function only supports UTF-8 format. if there is a Chinese character in the middle, you can use iconv or mb to convert it to the UTF-8 and then perform json_encode, so there will be no problem.

Step 2: parse the data. We also use a php json processing function json_decode (). The code is as follows:

The code is as follows:

// JSON format data is represented by arrays in php. $ Arr = array ( 'Firstname' => iconv ('gb2312', 'utf-8', 'sincerity '), 'Lastname' => iconv ('gb2312', 'utf-8', 'Do Not Disturb '), 'Contact '=> array ( 'Email '=> 'fcwr @ bKjia. c0m ', 'Website' => 'http: // www. bKjia. c0m ', ) ); // Encode the array into JSON data format $ Json_string = json_encode ($ arr ); // Decodes JSON data. the decoded data is not in JSON format and cannot be output directly using echo. $ Obj = json_decode ($ json_string ); // Forcibly convert to array format $ Arr = (array) $ obj; // Call the data in the array Echo iconv ('utf-8', 'gb2312', $ arr ['firstname']); Echo' '; // Output array structure Print_r ($ arr ); ?>

Okay, the instance will talk about it here.
Json_decode () refer to http://www.bKjia. c0m/phper/18/32827 .htm
Json_encode () reference http://www.bKjia. c0m/phper/18/32827 .htm

The functions merge () and json_encode () are much easier to operate. you need to learn more...
