But, as it seems you want the output to be with {}, you better make sure to force json_encode() to encode as object, by passing the JSON_FORCE_OBJECT constant. $post_data = json_encode(array('item' => $post_data), JSON_FORCE_OBJECT); {} brackets specify an object and [] are used for arrays according to JSON specification JSON to PHP Using json_decode. PHP's json_decode function takes a JSON string and converts it into a PHP variable. Typically, the JSON data will represent a JavaScript array or object literal which json_decode will convert into a PHP array or object. The following two examples demonstrate, first with an array, then with an object
Example JSON to PHP Object <?php // JSON string $someJSON = '[{first_name:Bikash,gender:male},{first_name:Dev,gender:male},{first_name:John Doe,gender:female}]'; // Convert JSON string to Object $someObject = json_decode($someJSON); echo <pre>; print_r($someObject); // Dump all data of the Object echo $someObject[0]->first_name; // Access Object data ?> Regardless, bringing that JSON back into an object using json_decode() will give you just a std object, and the only way I've found to get it into the proper object type is to use a constructor that instantiates the object the way it's supposed to be (see __construct($var) above). Like this: <?php $newKit = new Kit (json_decode ($t));?> JSON laden und in ein PHP Objekt umwandeln. Durch die Funktion json_decode, lässt sich ein JSON Objekt, welches als String vorliegt, in ein PHP Objekt umwandeln Wenn true werden JSON-Objekte als assoziative Arrays zurückgegeben; Wenn false werden JSON-Objekte als Objekte zurückgegeben. Wenn null werden JSON-Objekte als assoziative Arrays oder Objekte zurückgegeben, abhängig davon ob JSON_OBJECT_AS_ARRAY in den options gesetzt ist. depth.

You can parse or read JSON data from JSON object or any JSON file using PHP json_decode() method. Different examples of parsing JSON data using PHP are given below. Example-1: In the following example, JSON data is assigned in a variable and PHP json_decode() method is used to read the data in PHP format
JSON is the format I use the most when it comes to data transfer. In almost every case I serialize my data with json_encode and at some point in time I use json_decode to get the data back into a somehow structured format.. For example I'm trying to encode/decode a class called Person.The encoding part is easy, add the JsonSerializable interface to the model and implement the JsonSerialize. Elasticsearch-PHP [7.x] » Dealing with JSON arrays and objects in PHP « Deleting documents Breaking changes from 6.x » Dealing with JSON arrays and objects in PHPedit. A common source of confusion with the client revolves around JSON arrays and objects, and how to specify them in PHP. In particular, problems are caused by empty objects and arrays of objects. This page shows you some common. There is a solution however. A Jsonserializable interface was added in PHP 5.4 which allows you to accomplish this. class Person implements JsonSerializable { protected $id; protected $name; public function __construct(array $data) { $this->id = $data['id']; $this->name = $data['name']; } public function getId() { return $this->id; } public.
The json_decode () function is used to decode a JSON object into a PHP object or an associative array. The json_decode () function returns an object by default. The json_decode () function has a second parameter, and when set to true, JSON objects are decoded into associative arrays Then, you can convert your error object to JSON with json_encode $error = new MyError(Page not found, 404, Unfortunately, the page does not exist); echo json_encode($error); Check out the example her To convert a valid JSON string back, you can use the json_decode() method.

Returns the value encoded in JSON in appropriate PHP type. If the JSON object cannot be decoded it returns NULL: PHP Version: 5.2+ PHP Changelog: PHP 7.3: Added JSON_THROWN_ON_ERROR option PHP 7.2: Added JSON_INVALID_UTF8_IGNORE, and JSON_INVALID_UTF8_SUBSTITUTE options PHP 5.4: Added JSON_BIGINT_AS_STRING, and JSON_OBJECT_AS_ARRAY option Example-3: Print JSON using JSON_PRETTY_PRINT option and <pre> tag. The formatting that is applied in the previous example can be done by using 'pre' tag in place of header() function. Create a file named exp3.php with the following code. In this example, starting the 'pre' tag is used before generating JSON data. The output will be similar to the previous example
