JSON(JavaScript Object Notation) is a lightweight data exchange format. Easy to read and write. It is also easy to parse and generate machines. It is based on a subset of JavaScript programming language, standard ECMA-262 3rd edition-December 1999. JSON uses a completely language-independent text format, but it also uses a habit similar to the C language family (

a PHP object instead of an array. Like what: $json = ' {' A ': 1, ' B ': 2, ' C ': 3, ' d ': 4, ' E ': 5} '; Var_dump (Json_decode ($json)); The result is to generate a PHP object: Object (StdClass) #1 (5) {["a"] + int (1) ["b"] = + int (2) ["c"] = = Int (3) ["D"] = + int (4) ["E" ] = = Int (5)} If you want to force a PHP associative array to be generated, jso

data structure. Here is an example: $json = ' {' foo ': 12345} '; $obj = Json_decode ($json); Print $obj->{' foo '}; 12345 Typically, Json_decode () always returns a PHP object, not an array. Like what: $json = ' {' A ': 1, "B": 2, "C": 3, "D": 4, "E": 5} '; Var_dump (Json_decode ($json));

Parses an instance in json format data 2 and a json instanceParsing instances in json format data 2 Json is a commonly used data transmission format on mobile platforms. In this example, two Json format file generation and parsing methods are provided.The first method is to

'; 　　private $private_ex = 'this is private!'; 　　protected $protected_ex = 'this should be protected';　　　public function getErrorCode() { 　　　　return self::ERROR_CODE; 　　} } Now, perform json conversion on the instance of this class: 12345 $foo = new Foo; $foo_json = json_encode($foo); echo $foo_json; The output result is 1 {"public_ex":"this is public"} As you can see, except the public variable

results @ Param {String | Number} space (optional) add indentation, spaces, and line breaks to the returned JSON text to make it easier to read Note: If the value has the toJSON method, the JSON. stringify function uses the return value of this method. If the return value of the toJSON method is undefined, no member is converted. This allows the object to determine its own j son representation. V

For example: The Code is as follows: $ Json = '{"a": 1, "B": 2, "c": 3, "d": 4, "e": 5 }';Var_dump (json_decode ($ json )); The result is to
