About the Zend Framework's approach to working with JSON data

This article mainly introduced the Zend Framework processing JSON data method, combined with the example form analysis of the Zend Framework for the JSON-related operation class, the need for friends can refer to the following

This example describes how the Zend Framework processes JSON data. Share to everyone for your reference, as follows:

JSON separators and meanings

{} is used to implement the object's inclusion, and the object is enclosed in curly braces
, commas are used to separate different properties of an object, or elements of an array
[] to hold the array, the array will be stored in brackets
: A value that represents a key/value pair, a key before a colon, and a value for the key after a colon

JSON sample

{"  AddressBook": {    "name": "Mary Lebow",    "address": {      "street": "5 Main Street", "City      ": "San Diego , CA ",      " Zip ": 91912    },    " Phonenumbers ": [      " 619 332-3452 ",      " 664 223-4667 "    ]  }}

Using JSON

Syntax: $json = Zend_json::encode ($phpNative);
Description: Where the parameter $phpnative is a common data type for PHP, it can be an array, an object, or other type of data.
The function return value is $json to a string that conforms to the JSON format.

Example:

<?phprequire_once ("zend/json.php"); $temp = Array (  "a" =>0,  "B" =>1,  "C" =>array (    "c-1" = >21,    "C-2" =>22,    "c-3" =>23,  ),  "D" =>3); $json = Zend_json::encode ($temp); echo "Temporary array contents are: "Echo" <pre> ";p Rint_r ($temp); echo" </pre> "echo" is converted to JSON format: "; echo" <pre> ";p Rint_r ($json); echo "</pre>";

The result is:

The temporary array contents are: Array (  [A] = 0  [b] = 1  [c] = = Array    (      [c-1] = [      c-2]      = [C-3] =  [d] + 3) converted to JSON format content is: {"A": 0, "B": 1, "C": {"c-1":, "c-2":, "c-3": +}, "D": 3}

Decoding JSON to normal data

Syntax:$phpNative = Zend_json::d ecode ($json);

Example:

<?phprequire_once ("zend/json.php"); $json = "{  \" Addressbook\ ": {    \" name\ ": \" zhangsan\ ",    \" Address\ ": {      \" street\ ": \" Chang an jie\ ",      \" city\ ": \" beijing\ ",      \" zip\ ": 100001    },    \" phonenumbers\ ": [      \ "010-12345678\",      \ "010-11111111\"    ]  }} "; echo" before decoding: "echo" <pre> ";p Rint_r ($json); echo" </ Pre> "; $native = Zend_json::d ecode ($json); echo" after decoding: "; echo" <pre> ";p Rint_r ($native); echo" </pre> ";

The output is:

Before decoding: {  "AddressBook": {"    name": "Zhangsan",    "address": {      "street": "Chang an Jie", "City      ": " Beijing ",      " Zip ": 100001    },    " Phonenumbers ": [      " 010-12345678 ",      " 010-11111111 "    ]  }} After decoding: Array (  [addressbook] = = Array    (      [Name] = + Zhangsan      [address] = = Array        (          [Street] = Chang an Jie          [city] = Beijing          [zip] = 100001        )      [phonenumbers] = Array
   (          [0] = 010-12345678          [1] = 010-11111111        )    ))

Description

When you use this method to decode the JSON content, you can decode it to an array or decode it as an object.

Specific Zend_json: The second parameter of the:d Ecode () method is determined.

The syntax format is as follows

Phpnative=zendjson::d ecode (Phpnative=zendjson::d ecode (Json,zend_json::type_object);

The result of the previous example decoding to an object is

After decoding: StdClass object (  [AddressBook] = StdClass object    (      [name] = Zhangsan      [Address] = StdClass Object        (          [Street] = Chang an Jie          [city] = Beijing          [zip] = 100001        )      [ Phonenumbers] = Array        (          [0] = 010-12345678          [1] = 010-11111111        )    ))

Summary:

The use of JSON is still relatively simple and requires JSON for interface applications. It can be used in different languages. Data can be transferred flexibly. Works like XML, but saves bandwidth over XML.
