Json 做为一种轻量级的数据交换格式,开始受到亲睐,有与 XML 抢地盘的风头。而让人高兴的是,php也把 json 序列化数据的功能内置成函数了,这让想使用json的 PHPCoder 备感方便。
美中不足的是,json_encode / json_decode 系列函数只有在 php5.2 以上才有。这让立志开发兼容性强的PHP系统的coder很头痛。
幸好,已经有人把 json 的方法封装成 php4.x 系列甚至更低的版本都可以执行的类了。这里要先谢谢先驱了。让我们可以踩在巨人的肩膀上走向成功。

使用方法:
if( function_exists("json_encode") )
{
return json_encode($phparr);
}
else
{
require_once ROOT."include/json.class.php";
$json = new Services_JSON;
return $json->encode($phparr);
}
