想提取message的值,如此处是ok,还有最有一条记录的时间和内容,如此处分别是2012-07-07 17:35:24和北京市通州区城区/业务员收件/取件人:张蒙,该如何实现?

------解决方案--------------------
假定编码为utf-8的,否则还需$s=iconv('gbk', 'utf-8', $s);

$s = 你的那个串
$s = strtr($s, "'", '"'); //转成php可识别的 json
$t = json_decode($s);
echo $t->message; //ok
echo $t->data[9]->context; //北京市通州区城区/业务员收件/取件人:张蒙



------解决方案--------------------
你可以先用explode函数
------解决方案--------------------
PHP code

$current= strtr($current0, "'", '"');
$json = json_decode($current);
echo $json->message;
$length=count($json->data);;
$bottom=$length-1;
echo $json->data[$bottom]->context; <div class="clear">
                 
              
              
        
            </div>
