JSON in PHP using _php tutorial

Starting with version 5.2, PHP native provides the Json_encode () and Json_decode () functions, which are used for encoding, which is used for decoding.

Json_encode ()

This function is primarily used to convert arrays and objects into JSON format.

$arr Array (' a ' = = ' A ', ' b ' = ' = ' B ', ' c ' = ' C ', ' d ' = = ' d ', ' e ' = ' e '); echo json_encode ($arr);

Output Result:

JSON accepts only utf-8 encoded characters, and Json_encode () parameters must be utf-8 encoded.

class person{    public$name;      Public $age ;      Public $height ;     function __construct ($name,$age,$height)    {         $this $name ;         $this $age ;         $this $height ;        }   } $obj New person ("Zhangsan", 20,100); $foo _json = Json_encode ($obj); Echo $foo _json;

Output Result:

When a property in a class is a private variable, it is not output.

Json_decode ()

This function is used to convert the JSON text to the appropriate PHP data structure.

$json = ' {' A ': ' Hello ', ' B ': ' World ', ' C ': ' Zhangsan ', ' d ': ', ' e ': "; Var_dump (Json_decode ($json));

Output Result:

Typically, Json_decode () always returns a PHP object.

To an array:

$json = ' {' A ': ' Hello ', ' B ': ' World ', ' C ': ' Zhangsan ', ' d ': ', ' e ': "; Var_dump (Json_decode ($json, ture));
