PHP转换成JSON数组，及PHP解析JSON数组。

<?php
class Emp {
public $name = "";
public $hobbies  = "";
public $birthdate = "";
}
$e = new Emp();
$e->name = "sachin";
$e->hobbies  = "sports";
$e->birthdate = date('m/d/Y h:i:s a', "8/5/1974 12:20:03 p");
$e->birthdate = date('m/d/Y h:i:s a', strtotime("8/5/1974 12:20:03"));
echo json_encode($e);
?>

{"name":"sachin","hobbies":"sports","birthdate":"08/05/1974 12:20:03 pm"}

<?php

$postArray ='[{"data":{"hello":"world"},"type":"1234","date":"2012-10-30 17:6:9","user":"000000000000000","time_stamp":1351587969902}, {"data":{"hello":"world"},"type":"1234","date":"2012-10-30 17:12:53","user":"000000000000000","time_stamp":1351588373519}]';

$de_json = json_decode($postArray,TRUE);
$count_json = count($de_json);
for ($i = 0; $i < $count_json; $i++)
{
//echo var_dump($de_json);

$dt_record = $de_json[$i]['date'];
$data_type = $de_json[$i]['type'];
$imei = $de_json[$i]['user'];
$message = json_encode($de_json[$i]['data']);

}

?>
