PHP的JSON類庫我使用的是Services_JSON，沒什麼特別的優點，也沒什麼明顯的缺點，對付用足矣。
建立檔案data.php：
<?php
include("JSON.php");
$data = array(
array('name' => mb_convert_encoding('老王', 'UTF-8', 'GBK'), 'age' => '28'),
array('name' => mb_convert_encoding('小黃', 'UTF-8', 'GBK'), 'age' => '27')
);
$json = new Services_JSON();
echo $json->encode($data);
?>
Javascript解析JSON我使用的是Jquery，直接使用Javascript的eval則有個地方要注意：
var myObject = eval('(' + myJSONtext + ')');

alert("姓名：" + json[i].name);
alert("年齡：" + json[i].age);
}
});
});
