PHP json_decode（）返回有效json上的空数组,php,json,Php,Json,我已经读了很多关于堆栈溢出的问题，但是我仍然无法理解。我从一个我不控制的服务的webhook中获得以下JSON。我将数据读入一个PHP变量，如下所示： $postData=文件\u获取\u内容'php://input'; 我将$postData输出到一个日志文件以查看POST请求的内容，如下所示： { "v": 1, "matches_filters": { "current": [ 1, 10 ] }, "meta": { "v

我已经读了很多关于堆栈溢出的问题，但是我仍然无法理解。我从一个我不控制的服务的webhook中获得以下JSON。我将数据读入一个PHP变量，如下所示：

$postData=文件\u获取\u内容'php://input';

我将$postData输出到一个日志文件以查看POST请求的内容，如下所示：

我通过jsonlint.com运行了上面的JSON，结果显示它是有效的。我尝试使用substr$postData，3，正如在其他一些SO问题中所建议的那样，以消除字符串上的BOM编码，但这只是切断了JSON字符串的前3个字符

var_dumpjson_decode$postData，true；只返回空白。我可以看到一个数组是通过输出json_decode$postData创建的，为一个变量true，然后记录它，但它是完全空的。json_last_error返回0，php错误日志中不会显示任何警告或错误

我不明白为什么JSON字符串没有正确地进入带有JSON_decode的数组。。。为什么json_last_error为0而数组仍然为空。。。任何帮助都将不胜感激。

尝试此公共函数uu decode_data{$raw_data=fopen'php://input“，'r'；$json_data=fgets$raw_data；$decoded=json_decode$json_data，true；return$decoded；}您的服务器上运行的是什么版本的PHP？@qʞzoɹǝɟ，我知道它是这样工作的，当我将日志输出中的字符串复制/粘贴到字符串变量时，效果很好。我的问题是，当我将数据读入变量时，有些东西不起作用，我将变量记录到日志文件中，而不是输入，因此我要确保知道变量的内容，然后将变量传递给json_decode，或者对输入本身使用json_decode。这让我觉得这是一个编码问题，但我在别处读到的BOM修复也不起作用。@KirkLogan我们的服务器有PHP版本5.4.45
