JSON (JavaScript Object Notation, http://json.org) is a lightweight data-interchange format.
|
||||
It is easy for humans to read and write. It is easy for machines to parse and generate.
|
||||
It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
||||
This feature can also be found in Python. JSON is a text format that is completely language independent
|
||||
but uses conventions that are familiar to programmers of the C-family of languages, including
|
||||
C, C++, C#, Java, JavaScript, Perl, TCL, and many others. These properties make JSON an ideal
|
||||
data-interchange language.
|
||||
|
||||
This package provides a simple encoder and decoder for JSON notation. It is intended for use
|
||||
with client-side Javascript applications that make use of HTTPRequest to perform server
|
||||
communication functions - data can be encoded into JSON notation for use in a client-side
|
||||
javascript, or decoded from incoming Javascript requests. JSON format is native to Javascript,
|
||||
and can be directly eval() with no further parsing overhead.
|
||||
|
||||
## So, what is the goal with this version?
|
||||
|
||||
While this version doesn't have a better performance than json_encode() and json_decode() available as extension,
|
||||
it has the next features:
|
||||
|
||||
[x] it doesn't require an extension. If you can't install an extension, then you can use this version.
|
||||
[x] **it works with json with unquoted keys** (for example javascript notation)
|
||||
[x] It is a simple file with no dependency.
|
||||
|
||||
## Usage
|
||||
|
||||
### Getting started
|
||||
|
||||
* Install the library using composer (or you could download Services_JSON.php manually)
|
||||
```shell
|
||||
composer require eftec/services_json
|
||||
```
|
||||
* Include the dependency
|
||||
```php
|
||||
use eftec\ServicesJson\Services_JSON;
|
||||
include '../vendor/autoload.php';
|
||||
$s=new Services_JSON();
|
||||
```
|
||||
|
||||
* And creates a service class
|
||||
```php
|
||||
$s=new Services_JSON();
|
||||
```
|
||||
See the folder examples for further examples
|
||||
|
||||
### Decode
|
||||
|
||||
Decode transform (decodified) a json string into a stdclass or an associative array
|
||||
|
||||
```php
|
||||
$s=new Services_JSON();
|
||||
$json='{"hello":{"a":2,"b":3},"world":[1,2,3,"aaa"]}';
|
||||
var_dump($s->decode($json)); // as stdclass
|
||||
var_dump($s->decode($json,true)); // as array
|
||||
```
|
||||
It also works with unquoted keys
|
||||
|
||||
```php
|
||||
$s=new Services_JSON();
|
||||
$json='{hello:{a:2,b:3},world:[1,2,3,"aaa","bbbb"]}'; // the keys are unquoted.
|
||||
var_dump($s->decode($json)); // as stdclass
|
||||
var_dump($s->decode($json,true)); // as array
|
||||
```
|
||||
|
||||
### Encode
|
||||
|
||||
Encode transform a value (array, object, primitive value, etc.) into a json expression (a string)
|
||||
|
||||
```php
|
||||
$array=["hello"=>['a'=>2,'b'=>3],'world'=>[1,2,3,"aaa","bbb"]];
|
||||
$obj=(object)$array;
|
||||
var_dump($s->encode($array)); // encode an associative array
|
||||
var_dump($s->encode($obj)); // encode an object
|
||||
```
|
||||
|
||||
|
||||
## Changelog
|
||||
|
||||
* 1.1
|
||||
* It works with PHP 7.2 and higher.
|
||||
* It doesn't require PECL to work.
|
||||
* The code was cleaned
|
||||
* web header is removed.
|
||||
* Method decode() could return an associative array.
|
||||
* 1.0.3-1.0.0 PECL version. It only works with PHP 4.x and PHP 5.x
