PHP Class FastJSON, wordpress-console
FastJSON,
simple and fast Pear Service_JSON encoder/decoder alternative
[http://pear.php.net/pepr/pepr-proposal-show.php?id=198]
---------------------------------------
This class is about two time faster than Pear Service_JSON class.
This class is probably not powerful as Service_JSON but it has
no dependencies and converts correctly ASCII range 0x00 - 0x1F too.
There's any string convertion, just regular RFC specific characters are converted
into \u00XX string.
To don't have problems with other chars try to use utf8_encode($json_encoded_string).
To recieve correctly JSON strings from JavaScript use encodeURIComponent then
use, if is necessary, utef8_decode before JS to PHP convertion.
decode method doesn't returns a standard object class but You can
create the corret class directly with FastJSON::convert method
and with them You can manage JS Date objects too.

Special FastJSON::convert method Informations
_______________________________________
---------------------------------------
This method is used by FastJSON::encode method but should be used
to do these convertions too:
- JSON string to time() integer:
FastJSON::convert(decodedDate:String):time()
If You recieve a date string rappresentation You
could convert into respective time() integer.
Example:
FastJSON::convert(FastJSON::decode($clienttime));
i.e. $clienttime = 2006-11-09T14:42:30
returned time will be an integer useful with gmdate or date
to create, for example, this string
Thu Nov 09 2006 14:42:30 GMT+0100 (Rome, Europe)
- time() to JSON string:
FastJSON::convert(time():Int32, true:Boolean):JSON Date String format
You could send server time() informations and send them to clients.
Example:
FastJSON::convert(time(), true);
i.e. 2006-11-09T14:42:30
- associative array to generic class:
FastJSON::convert(array(params=>values), new GenericClass):new Instance of GenericClass
With a decoded JSON object You could convert them
into a new instance of your Generic Class.
Example:
class MyClass {
var $param = "somevalue";
function MyClass($somevar) {
$this->somevar = $somevar;
};
function getVar = function(){
return $this->somevar;
};
};
$instance = new MyClass("example");
$encoded = FastJSON::encode($instance);
{"param":"somevalue"}
$decoded = FastJSON::decode($encoded);
$decoded instanceof Object => true
$decoded instanceof MyClass => false
$decoded = FastJSON::convert($decoded, new MyClass("example"));
$decoded instanceof Object => true
$decoded instanceof MyClass => true
$decoded->getVar(); // example
