用PHP解析JSON数据....大量的数据可能低于

Question

是我试图解析并投入DB数据集...我使用此代码

$json = json_decode($string); 
$json[0]['segments']['layover'] gives access error... 

还的sizeof（$ JSON）没有返回...

$ JSON没有返回null，检查，有回声的var_dump打印（$ JSON）

我试图通过这个的foreach ...不行..试过数组类型并说我非法访问stdIN对象......有没有像DOMDocument（）一样简单地通过json？

--- JSON

Answer 1

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？或者如果它是错误的，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...

似乎在最后有一个错位的字符。而不是逗号“，”它应该是一个关闭阵列“]”

Answer 2

你没有说为什么json_decode不起作用。如果JSON太大而不能在这里发布，只需使用pastebin或类似的东西。

我认为它不工作的原因是因为你超过了PHP内存津贴，您可以解决此通过增加最大内存PHP可以使用，例如：

的ini_set（“memory_limit的”，'16M “）;

但是我不会推荐这样做，如果这个代码将被大量的用户运行。也许如果你给我们一些上下文，我们可以给你一个绕过json_decode需求的替代解决方案。

Answer 3

json_decode需要第二个参数来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
