    [{"data":{"hello":"1222"},"type":"12349999","date":"2014-10-30 17:6:9","user":"123","time_stamp":1351587969902}, {"data":{"hello":"world"},"type":"777","date":"2011-10-30 17:12:53","user":"0000","time_stamp":1351588373519}]
但是有的时候我们会遇到不带双引号，例如下面的：

{result:133,total:154,Page:0,list:[{Prdh:"abcde"}]}
在php中用json_decode是无法解析这种不带双引号的，不规则的json格式。那我们只能把不正规变成正规，才能进行解析。利用下面代码就可以将json变成正规格式：

function json_decode_new($str, $m=false) {
  if(preg_match('/\w:/', $str))
    $str = preg_replace('/(\w+):/is', '"$1":', $str);
  return json_decode($str, $m);
}
主要是应用了一个正则表达式。
二、ie7浏览器对于json格式要求比较严格，如果json写的格式不规范就会报错，我遇到的问题是提示提示缺少标识符、字符串或数字。当时我的json格式是这个样写的

var jsonstr={'name':'ceshi','title':'555'}
在我们看来是没有错误的，但是在ie7下面不行，我们必须在最后加上逗号，变成下面这种：

var jsonstr={'name':'ceshi','title':'555',}
