由于涉及到隐私，不好向你索取隐去的数据。自然就不能运行你的代码
但你总可以贴出 $json 的值吧print_r(json_decode($str)); //如果直接转浏览器上的json数据可以显示
你在浏览器“查看网页源代码”中得到的也可以转码？
双引号被转义了吧？
浏览器打印出来的json的值我已经贴出来了就是保存在$str变量里。查看源码发现多了好多没用的东西？<script type="text/javascript">

你贴出的不是 html 代码吗？
你说的 json 数据在哪里？由 js 动态读取的？
源码里多了这些东西，我发现我正则匹配错了。如果我要匹配<script type="json" id="json-msgList"></script>中的内容应该怎么写？
preg_match("/<script type=\"json\" id=\"json-msgList\">(.+?)<\/script>/s",$contents,$json);
