下面是我试图解析并放入db的数据集......我正在使用此代码
$json = json_decode($string);
$json[0]['segments']['layover'] gives access error...
sizeof（$ json）也不返回任何内容......
$ json不返回null，被选中，用echo var_dump（$ json）打印
我试图通过这个来解决...不起作用..尝试了一个数组类型并且说我是非法访问stdIN对象...有没有像DOMDocument（）一样容易走过json？

json_decode接受第二个参数将数据作为关联数组而不是对象返回。这将解决您的问题。
$json_array = json_decode($string,true); // returns 'normal' php array.
$json = json_decode($string); // returns php object hierarchy
答案 1 :(得分：0)
http://json.parser.online.fr/报告您的数据意外结束。你真的有真实的数据吗？或者如果是错的，你是如何产生它的？生成脚本中可能存在错误，因为它不完整......
最后似乎有一个错位的角色。而不是逗号“，”，它应该是一个结束数组“]”
答案 2 :(得分：0)
你没有说为什么json_decode不起作用。如果JSON太大而无法发布，请使用pastebin或类似内容。
我认为它不起作用的原因是因为你超出了PHP的内存容量，你可以通过增加PHP可以使用的最大内存来解决这个问题，例如：
的ini_set（ 'memory_limit的'， '16M'）;
但是，如果此代码将由大量用户运行，我不建议这样做。也许如果你给我们一些上下文，我们可以给你一个替代解决方案，绕过json_decode的需要。
