怎么会有错呢，简单的json读取

$pingluninfo =  {

}
EOT;

$pingluninfo = json_decode($pingluninfo, true);
if(!$pingluninfo) {

?>
总是输出 错误的数据格式

看着json 不对劲。
中文在json_encode 后不是这样的吧

<?php $pingluninfo = <<<EOT{    "title":"123",    "url":"http://localhost/?p=9",    "ttime":1401327899094,    "sourceid":"9",    "parentid":"0",    "categoryid":"",    "ownerid":"",    "metadata":"",    "comments":[        {            "cmtid":"358",            "ctime":1401327899094,            "content":"2013年8月1日18:36:29 O(∩_∩)O~",            "replyid":"0",            "user":{                "userid":"1",                "nickname":"admin",                "usericon":"",                "userurl":"",                "usermetadata":{                    "area": "北京市",                    "gender": "1",                    "kk": "",                    "level": 1                }            },            "ip":"127.0.0.1",            "useragent":"Mozilla/5.0 (Windows NT 6.1; rv:22.0) Gecko/20100101 Firefox/22.0",            "channeltype":"1",            "from":"",            "spcount":"",            "opcount":"",            "attachment":[                {                    "type":1,                    "desc":"",                    "url":"http://img.sohu.itc/xxxx"                }            ]        }    ]}EOT;$pingluninfo = json_decode($pingluninfo, true);if(!$pingluninfo) {    die('错误的数据格式');}echo "<pre class="brush:php;toolbar:false">";print_r($pingluninfo);echo "

请把引号补齐！
"ttime":1401327899094, 应为 "ttime":"1401327899094",
其他类同

新版的？怎么讲？

我把上面说测试正常的代码复制到我那里，就是提示数据错误。
看来真是环境问题啊
