我有一个很大的多维JSON数组，我试图用PHP解析（由于约束需要PHP）。我有一个变量中的下面，然后我在这个字符串上做一个高级多维PHP JSON解析问题
json_decode。我已经尝试过，但没有真正保存为数组。
$ json = json_decode（$ result，true）;
然后我尝试和借鉴，甚至一些简单的像
$ JSON [ '数据'] [ 'cfgversion']，它不工作。我也试过没有真正使用$ json->数据 - > cfgversion
我所想要知道的就是
“port_overrides”：[{ “port_idx”：6， “portconf_id “： “59d18fe9b6081ed3f75d3355” }，{ “AUTONEG”：真， “隔离”：假， “名称”： “端口8”， “op_mode”： “开关”， “poe_mode”： “直通” ， “port_idx”：8， “portconf_id”：“575797d9429272985a1db175”， “stormctrl_bcast_enabled”：假， “stormctrl_mcast_enabled”：假的， “stormctrl_ucast_enabled”：假 }]，
我想修改像portconf_id件事数组中，然后将其推回（这是一个宇辉开关）
任何想法都会很棒。我看了其他JSOn PHP解析答案，他们似乎不适用于我的下面。提前致谢。

它的一个数组，你应该做'$ JSON [ '数据'] [0] [ 'cfgversion']' –
是的，就是这样非常感谢，所以我可以弄清楚我想用PHP中的数组完成很多其他事情。 – Type11
愚蠢的问题，但我如何选择你的答案作为这里的正确答案？我无法找到允许的位置 – Type11
